Hi friends just a quick question,
does the centroid of an object change if it is submerged in a fluid and is on an incline?
Or indeed does the centroid of an object ever change when in a fluid or inclined?
Hi friends - I'm at a lost on this particular problem which reads:
a manometer consists of a U-tube, 7mm internal diameter, with vertical limbs with an enlarged upper end of 44mm diameter. the left-hand limb and the bottom of the tube are filled with water and the top of the right hand limb...
Hello friends I am again in need of some asistance,
The Question is as follows:
The pressure head in a gas main at a point 120 m above sea level is equivalent to 180 mm of water. Assuming that the densities of air and gas remain constant and equal to 1.202 kg m^-3 and 0.561 kg m^-3...
a question about the engineers bending equation,
M/I = E/R = (sigma)/y
so take for example a beam with a rectangular cross section with depth 'b'.
Will y then equal b/2 ? As y is measured from the neutral axis?
Thank you in advance for your time,
$50 - That is the market price, but if we are talking about my limit I would proabbly go $100. Is this fight happening soon is it? oh btw I prefer to watch from comfort of my home - you'd have to pay me to go to the stadium.
Hello my friends, so I am once again confused :frown:
Is the second moment of area a universal property of a beam i.e the beams cross section?
So what i mean to say is - if i have a beam and it is curved with a rectangular cross section, and take this same beam and ensure it to be now straight...
If i wanted to calculate I in this problem would it simply be as follows:
I = (pi*P*R^(3)) / (2E) ?
and thus substituting values in if we take
E = 69 GPa
R = 150 mm
P = 0.1 N
we get I = 1.28 *10^(-14)m^(4)
The answer i get in my textbook however reads - 1.63*10^(-28)m^4
I have this problem it reads:
A random variable X is defined to be the larger of the two values when two dice are thrown, or the value if the values are the same. Find the probability distribution for X.
So I don't know how to state "X is defined to be the larger of the...
I have this problem I'm having difficulty with,
it reads - simplify the following expression
( ( x + 2 ) / (x^(2) - 2x) ) - ( (x) / (x^(2) - 4) )
it wants me to simplify it into ( 4(x + 1) ) / ( x(x - 2) ( x + 2) )
I can't get it to...
so i have this problem it reads:
how many solutions does the following equation have
Log_a(x+3) + Log_a(x-4) = Log_a(8)
ok so first i put all the logs on one side of the equation and solve for x after using log laws,
and i get x = 4 and x = -3, however plugging...
I have this question which stumps me because i have no idea what its actually asking for :S - it reads:
calculate the value of the first derivative of f(x) = x^(2) -3x - 1/x at x = 2.
In which interval does it lie?
(a) -x <= x < 0
(b) 0 <= x < 4
Hello my friends,
I have this problem and would appreciate someones help:
Determine all intervals where the following function is increasing or decreasing.
F(x) = -x^(5)+(5/2)x^(4)+(40/3)x^(3)+5
To determine if the function is increasing or decreasing we will need the...
so i have this problem:
A beam under test has a measured radius of curvature of 300 m. The bending moment applied to it is 8 Nm. The second moment of area is 8000 mm4. Calculate the modulus of elasticity for the material.
ok so using the engineers bending equation i have...
