An airplane propeller is 2.08 m in length (from tip to tip) and has a mass of 117 kg. When the airplane's engine is first started, it applies a constant torque of 1590Nm to the propeller, which starts from rest.
Question I:
What is the average power output of the engine during the first...
The problem I guess that I'm having is visualizing the problem, the way I visualize it is a pendulum starting from the 0 or 2(pi) section and swinging to the (pi). Is this the proper visualization? If so then the maximum height would be 2m's. Then in this case it would be KE_1+PE_1=KE_2+PE_2...
A stick with a mass of 0.170Kg and a length of 1.00m is pivoted about one end so it can rotate without friction about a horizontal axis. The meter stick is held in a horizontal position and released.
1) As it swings through the vertical, calculatethe change in gravitational potential energy...
With a system where Block A is on a horizontal and Block B is over the edge connected by a rope on a pulley, block A has mass = 2.10 , block B has mass = 0.410 , and the rope connecting them has a nonzero mass 0.162 . The rope has a total length 1.08 and the pulley has a very small radius...
