One cubic metre of water is placed under an absolute pressure of 7000 kPa. Calculate the volume at this pressure. The answer is .99682 but I do not know how to get it. I believe that it has to do with Compressibility and Elasticity.

Here is the link to it if you didnt the attached pic. http://i50.tinypic.com/33uy7sy.jpg

Is this what you mean (look at the attached picture).

Homework Statement How long would it take for the block to travel 10m starting from zero velocity? (i.e. T =?) (Look the the attached picture for the block and the position of it on the plane at 45 degree and 10 m from ground with the same slope) Theta = 45 degrees m = 1.0 kg f = 0.3...

0 ≤ θ ≤ 2n, 2sec(ϕ) ≤ ρ ≤ 4, 0 ≤ ϕ ≤ pi/4?

Ohhh... This is if I choose 0 ≤ θ ≤ π ?

I got the bounds for this, just a min ago. it will be 0 ≤ θ ≤ pi/4 and sec θ ≤ r ≤ 2cosθ. thanks anways.

In the xyz space, it would want the top half of the circle.

In the xy plane, the region is a circle with radius of 4. The yz and xz plane looks similar, it also a circle with radius 4 but there is a line z = 2, and we want the top of the circle. HELP! ME!

Homework Statement Using spherical coordinates, set up but DO NOT EVALUATE the triple integral of f(x,y,z) = x(x^2+y^2+z^2)^(-3/2) over the ball x^2 + y^2 + z^2 ≤ 16 where 2 ≤ z. Homework Equations x = ρ sin ϕ cos θ y = ρ sin ϕ sin θ z = ρ cos ϕ ρ^2 = x^2 + y^2 + z^2 ∫∫∫w...

Homework Statement is angle of twist and degrees rotation the same thing?? Homework Equations (angle of twist is TL/JG, units are rad. Degrees roation is found by using moment and integrating moment equation once. to get EI dw/dx = integral of Moment + C1 ) (Units are unit-less but u say its...

You would just take a material, say steel for example, and try and find the deflection function for it, see if the max deflection of the beam is 1" and max rotation is 1" ? Which torque equation would help me?
