Moments (stylized MOMents) is a Filipino celebrity talk show hosted by Gladys Reyes and aired on Net 25. It is a show for mothers and kids that feature the different bonding moments, child-rearing styles and the many facets of motherhood. It airs 7pm every Saturdays with replays on Mondays to Fridays at 10 A.M and Sundays at 11:30 AM / 12:30 PM.
I'm developoing one mechamical device, that we'll put two nutrunner in one gear. One spur gear will rotate the gear and put the nutrunner and one position. Each nutrunner will fix one bolt with 70Nm.
I need put one motor in pinion, but i need consider the moments to define de size of the motor...
M= F x d at layer 7, layers 8 - 12 has its centre of mass at middle of layer 10, which is where the weight of these layers would be acting. Not sure hoe to determine whether it would topple
Hello! I saw many paper extracting the magnetic dipole and electric quadrupole moments of the nuclei by performing RF/microwave spectroscopy on the rotational levels of a molecule. However, I can't seem to find paper measuring higher order moments. For example, the magnetic octupole moment has...
Hey all,
I am currently looking for some data on the resonant transition dipole moment for the Rydberg states of Strontium (in the literature, the square of the dipole moment is known as the "C3 coefficient"). If anyone could point me to some relevant papers that would be greatly appreciated.
Hi so with this question, I am really confused. Even from the start. Like it doesn't tell us where the force is acting on. From top of block, middle of block etc? And I know how to determine the direction of moment for something on a pivot, not in this scenario though. The answer is A. They did...
I have tried solving this by splitting the load into two parallel coplaner loads as the Hint below the question suggests but while i was computing the values i realized that, i'll have 4 variables with only 3 equations.
two forces and the two distances to forces from their respective axes.
i've...
A very simple (I thought!) question:
I'm just looking at the first part, finding the reaction at the hinge A.
Here is my annotated diagram, with the reaction and A resolved into it's X and Y components, the force at E labelled as Fe and the length of ED labelled as L.
Considering the body...

Could I please ask for help with the following question?
Four uniform rods of equal length l and weight w are freely jointed to form a framework ABCD. The joints A and C are connected by a light elastic string of natural length a. The framework is freely suspended from A and takes up the shape...
Attached is a Q from an AS mechanics paper. I'm perplexed about part (c) in which we are told that the tensions in the two cables are equal.
My physics brain says take moments about the CoM of the beam so eliminating the mass of the beam and making the moments of the two cables equal and...
Is there anyone out there who can help a newbie understand how to deal with Berry phase dipole moment data?
I ran a simulation to calculate dipole moments over time using the Berry phase method. The problem is that there are jumps in my data. There is an example at the end of this post (part...
Good morning!
I know this may sound a little odd, because there is a theorem regarding it, but i have this question.
Basically, a CFD analysis gives me the value of the forces and the moments, as a function of fuselage's orientation, in a particular frame of reference.
How can i calculate the...
I couldn't fit in the title, but this is with a hollow circular cross section
So currently I am trying to figure what occurs when two, perpendicular bending moments are applied to a hollow circular cross section (one about the z axis, and the other about y). I know that if I was dealing with a...
I have a problem as shown in the figure
So assume there is a cylinder rotating inside a stationally wall. There is a viscous fluid in between the gap of cylinder wall and outer stationary wall, similar to bearing.
The fluid has some velocity in axial direction also
the outer wall of cylinder...
Say that I have a continouos beam resting on top of column spanning across 3 column. The applied load is UDL on the beam, here's how the BMD look like. My question is whether the connection between the beam and column need to sustain the moment ? Which point need to sustain the moment ? All 3...
Moment about X2 to calculate force at X1:
x1 * 9 = (250 * 2)
Therefore, x1 = 500/9 = 55.5N
The book however gives force at x1 as 110N. So I figured I have not understood a concept somewhere
I think I have done this in an inefficient way. I assumed from the question that the three balances were of equal mass, though I'm not sure if I should have ignored their mass entirely. The correct answer is X = (62 + [2/9]) kg. Please help.
Hello! I read some papers about searching for induced atomic EDM. Finding such an EDM would imply a violation of the P and T-invariance (and hence CP). The way the derivation works (very roughly) is by assuming you have a PT-odd interaction in the hamiltonian (coming from a possible nuclear EDM...
The correct answer is 'B'.
I would like some clarification, in regard to the forces that exist in this moments problem.
General Queries:
1) Is there friction acting on the hinge in a downward direction (parallel to the wall)? Does the ramp being "smoothly hinged" to the wall mean there is no...
Hi
I need help with part d.
I think for part q(i) the force is horizontally and constant and equal to what I have found in part c. and for part d(ii) the force is upwards and equal to what I have found in part b.
I have tried this question but can't get my head around to doing part b)
This is the sketch I have drawn and I'm guessing 'x' is the distance that I have to fine that's perpendicular to force Fb, though I'm not sure if I have set it up correctly?
Any help would be appreciated! Thanks
Not sure if I answered this question right
I took my clockwise moments as +ve and counter-clockwise moments as -ve
Any help would be much appreciated! Thanks
1) are all Moments of forces and Moments of couples free vectors? Can I move the moment vector computed about point O to a new point "point B" without changing the system? To elaborate on the question, suppose Resultant Moment about point O is computed using several forces and the position...
I am trying to design a free standing stand for a pyrometer, which weighs 750g. The pyrometer needs to be 1.5 metres above ground level. The stand will be constructed entirely in steel. The layout of the stand is shown in the uploaded diagram Pyro_stand.gif. How can I derive expressions for the...
My first attempt revolved mostly around the solution method shown in this "site" or PowerPoint: http://physics.gmu.edu/~joe/PHYS685/Topic4.pdf .
However, after studying the content and writing down my answer for the monopole moment as equal to ##\sqrt{\frac{1}{4 \pi}} \rho##, I found out the...

Hey guys, I am stuck with this question in find the Tension in B and the moments around A. I have done plenty of 2d Tension questions but not a 3D one.
I have the characteristic function of the Cauchy distribution ##C(t)= e^{-(\mid t \mid)}##. Now, how would I show that the Cauchy distribution has no moments using this? I think you have to show it has no Taylor expansion around the origin. I am not sure how to do this.
How can I prove the Cauchy distribution has no moments?
##E(X^n)=\int_{-\infty}^\infty\frac{x^n}{\pi(1+x^2)}\ dx.##
I can prove myself, letting ##n=1## or ##n=2## that it does not have any moment. However, how would I prove for ALL ##n##, that the Cauchy distribution has no moments?

Hi
To calculate the moment of inertia of a large sphere , I can calculate I for a smaller sphere and then add to it , I for the spherical shell that added to the smaller sphere makes the larger sphere.
Does this general process apply to all shapes ? If so , does this process have a name ie. is...
A bending moment about an axis passing through a cross section arises due to an uneven distribution of stress across the cross section, like so:
I have read that any given bending moment is equivalent to a force couple applied about that axis. That is to say that the curly moment arrow on a...
I was reading through a set of notes and found something a little odd. The aim is to solve the beam structure shown below, which is massless and of length ##l##.
By considering the beam as a whole, we obtain ##A_y = P##, ##A_x = N## and by taking moments about A we see ##M_A = Pl##.
However...
I have been throwing everything I can at this. I believe that both the monopole and dipole are zero, but I have no clue as to how to evaluate the quadrupole moment.
I have a quesrion about forming the eqaution of moment equilibrium.
As shown in the picture at cut 1 there are 2 vertical forces and a bending moment. I expect V=A.
If I apply moment equilibrium about the point where the bending moment is, we get that Ay*x = M(1). But how about if I take moment...
The answer is 127.04g. I’m getting close but can’t get the answer.
Using 9.81 for gravity, the force where the balance is is 2.10(58146)N
As it is balanced
2.10N x 0.29m = W x 0.50m where 0.50 is the centre of mass
That gives W = 1.22N
= 124.5g?
Hello, I would like to find a mathematical demonstration of this problem. While I have always used it, I could never prove it. Given a charge or current distribution with axial symmetry the electric and magnetic dipole moment are null:

Hello all,
I was hoping someone could help me calculate the moment a tank wall experiences.
I have the following question:-
Tank contains water with dimensions:
4m Wide
12m Long
3m Tall
Determine the moment at the bottom of the long side at its centre.
I have drawn a sketch of the tank and...
Hello all;
I am trying to better understand the idea of Moments.
I know how to calculate moments i.e. Distance * Perpendicular Force.
My understanding was that moments were any push/pull force that creates a turning action about some point - that is what a moment is to me, I have shown this...
I have the moment of inertia for the core(initial) and full body(final) but my answer for the moment of inertia for the arms(initial) was incorrect.
Arms(initial) moment of inertia:(1/12)(6)(1.7^2)=1.445 this is incorrect for some reason
Core(initial) moment of inertia: .9558

I drew a diagram for the a) part
The person is h meters high
So GPE= 100 x 9.8x h
GPE= 980h j
KE = 980h when the person hits the see saw
KE=1/2mv²
980h=0.5 x 5 x v²
Now it v²=u²+2as
For the brick going up to 10m
v = 0
