Ah... It's starting to make more sense now, thanks. So since density is varying with the height we make it all one integral rather than separate ones. Part B is the same question except with the 4m on the ground on its point with the rectangle side up. I figured once I'd managed A, B would be...

Homework Statement A compressible liquid has density which varies with height. AT the level of h meters above the bottom, the density is 40(5 - h) kg/m3 a) The liquid is put in the containers below. The cross sections of the container are isosceles triangles. It has straight sides and...

Got it, thanks again! I'll be back in the future

Bah, I made a distributing error which would result in a -\Theta and +\Theta canceling out, thanks a lot! And thanks, it makes it easier to read Now when setting \frac{dE}{d\Theta} equal to zero I came up with: \Theta = \frac{-\mu}{-2\mu^{2} - \mu\Theta} Is this correct? Thanks again...

Optimization problem -- Trouble differentiating function Homework Statement The efficiency of a screw, E, is given by E=\frac{(\Theta - \mu\Theta^{2})}{\mu + \Theta} , \Theta > 0 where \Theta is the angle of pitch of the thread and \mu is the coefficient of friction of the material, a...
