What is Deflection: Definition and 525 Discussions
The vertical deflection (VD) or deflection of the vertical (DoV), also known as deflection of the plumb line and astro-geodetic deflection, is a measure of how far the gravity direction at a given point of interest is rotated by local mass anomalies such as nearby mountains. They are widely used in geodesy, for surveying networks and for geophysical purposes.
The vertical deflection are the angular components between the true zenith-nadir curve (plumb line) tangent line and the normal vector to the surface of the reference ellipsoid (chosen to approximate the Earth's sea-level surface). VDs are caused by mountains and by underground geological irregularities and can amount to angles of 10″ in flat areas or 20–50″ in mountainous terrain).The deflection of the vertical has a north-south component ξ (xi) and an east-west component η (eta). The value of ξ is the difference between the astronomic latitude and the geodetic latitude (taking north latitudes to be positive and south latitudes to be negative); the latter is usually calculated by geodetic network coordinates. The value of η is the product of cosine of latitude and the difference between the astronomic longitude and the longitude (taking east longitudes to be positive and west longitudes to be negative). When a new mapping datum replaces the old, with new geodetic latitudes and longitudes on a new ellipsoid, the calculated vertical deflections will change, too.
An electron with a kinetic energy 5000.0 eV (1 eV = 1.602×10-19 J) is fired horizontally over a charged plate with surface charge density +2.0 μC m-2. Taking the positive direction to be upwards (away from plate), what is the vertical deflection of the electron after it has traveled a horizontal...
i need to find the expression for the vertical direction of a beam in a cathode ray tube, using:
Va - accelerating voltage (between cathode &anode)
Vd - deflecting voltage
ly - effective length of deflecting plates
L - distance from end of plates to the screen
d...
I want to know in mechanics of materials what is the real objective of finding the deflections at various points in structures
like
1)deflection in the end of an axially loaded bar
2)vertical deflection along the beam length
3)beam slope along the beam length
5)torsion bar twist...
if i have a bending curve eqn of w'(x) = (q/6)<x-l>^3 - ql/4 <x-0>^3 - 3ql/4 <x-l>^2 + (9ql^3)/24
suppose to find the deflection of maximum of the beam, we have to set w'(0)=0 .Am i right??
then if it is right,how can i find the value for x on which the max bending occur because i don't...

Heat Deflection Coatings?
Hello all...
I was wondering if there was anything I could readily use as a coating for piston heads that will reflect the heat, such as ceramics or something that could be done at home?
Thanks
Hi I am in a competition where I have to use the deflection of a polystyrene beam to launch a projectile. Styrofoam is rather brittle but it is the only material we are allowed to use (it's cheap). I have a geometry all set but I was wondering if there is any possible way to treat the styrofoam...
We usually go over stuff after getting the assignments, so I have no clue how to start this question.
Figure 23N-14 shows the deflection-plate system of a conventional TV tube. The length of the plates is 3.2 cm and the electric field between the two plates is 10^6 N/C (vertically up). If the...
I'm really stuck on this questions, I don't even know where to start, can anyone help me?
A particle of mass m1 and velocity v1 collides with a stationary mass m2. After the collision, the two masses are deflected as shown in the diagram. Show that the angle of deflection Angle2 of m2 is...
Ok...I've struggled with this.
Let's say I'm dropping a mass from height h from the Earth's surface. Since I'm considering this as a non-inertial reference frame, I understand that there is an easternly deflection. I've done the calculation and end up with...
hey,
doing some revision and am getting slightly confused. When Rutherford did his experiment when did deflection occur and when did defraction occur? Is it when a alpha paticle is fired through gold foil (10^-6 thick) it defracted, and when alpha is fired through a necleus it deflected. Any...
If two cantilever beams are fixed at Left Hand Side (LHS) and joined to each other by means of a prop at RHS, how do i calculate the downwards vertical deflection of the bottom beam?
The solution i need to prove is (5WL^3)/(48EI)-top deflection.
However, i always seem to get a 7 where...

An electron is traveling horizontally at a speed of 8.70 x 10^6 m/s enters an electric field of 1.32 x 10^3 N/C between two horizontal parallel plates as described in the diagram.

How do I go about solving...
Deflection in "Plate"
Hi, question is kind of based on another problem I'm trying to solve. I'm trying to find a max force from a falling object without knowing deflection or time, but that thread is in College Homework Help, because the problem to me resembles it.
Anyways, my approach to...
I'm not sure the formula to use to calculate the deflection of a beam. Here's the information I have got.
Steel beam is 50 feet long. There is a 6,000 pound load in the middle(all other loads are disregarded. The modulus of elasticity is 29,000,000 psi. Moment of inertia is 850 inches^4...
an object of 3.8g moves @ 180m/s perpendicular to a magnetic field of (5x10^-5)T
the object possesses a net charge of (8.1x10^-9)C
by what distance will it be deflected from its pathe due to the magnetic field after it has traveled 1.0 km
so I'm guessing I'll have to find out the...
I eventually want to simulate cosmic ray propagation in a random magnetic field, but will start with a particle of some charge in a uniform field.
In order to simulate it, what I think needs to be done is to create a 3d array of points, with a value for the magnetic field magnitude and...
ok here's my problem(s)... I think the first one I'm missing something...

When a photon is deflected by the sun will it be deflected by twice the Newonian expectation for any distance from the centre of the sun or will the difference between the deflection relativity gives and Newtonian gravity gives change with distance?
I am inquiring if anyone knows the equation for how a photon is deflected by an electromagnetic field?
What is the official physical phenomenological terminology for this effect?
Can a pure strong magnetic field alone deflect a photon?
What is the equation that describes this effect?
When an elastic beam AB supports a block of weight W at a given point B, the deflection y_s (static deflection) is proportional to W. Show that if the same block is dropped form a height h onto the end B of a cantilever beam, the maximum deflection y_m = y_s(1 + (1+\frac{2h}{y})^\frac{1}{2})...

Here's a lil question:
If you have a rod of which an end is clamped to a table and you apply a force somewhere on the rod, what will the deflection be (in terms of difference in the height of the other end of the rod? For sure it will be proportional to the force and to some power of the...
