Homework Statement Here's a link to the pV-diagram I am using - http://session.masteringphysics.com/problemAsset/1396784/2/p16.7.jpg A heat engine takes 2.0 moles of an ideal gas through the reversible cycle abca, on the pV diagram shown in the figure. The path bc is an isothermal process...

The mass was varied over a few runs but for the initial calculation it started with m=1.002kg and the radius of the wheel & axle system is 0.237m. I found out what I did incorrectly though.. I said that ω=v_t/r= -0.4550 rad/s but then when I plugged ω back into that equation I said ω^2 =...

Values & calculation Alright, so the string is spun around the axle first of all. Data collected from Trial #1 is as follows: Time to fall = 10.33 seconds, distance fallen = 0.557 meters, radius of wheel/axle system is 0.237 meters. I ended up with M=4(mgh-0.5mv_f^2)/(r^2ω^2) , and with...

Homework Statement Find the mass, M, of a rotating wheel of radius r that has an attached mass, m, suspended by a string using conservation of energy. The mass is suspended a height, h, above the ground and it takes a time of t seconds to reach the ground.Homework Equations U_g,mass = K_f,mass...
