If a pulley is 57% efficient and you lift a 35kg box 5m how much work do you do?
1716.75 N*m
A crane that is 13m long and is at a 20 degree angle to the ground can hold a load of 296N. What is the torque on the crane?
1,316.10 N*m
A cylinder with a radius of 1.3m has a mass hanging from it with a weight on 13 N. When the weight is released it causes an angular acceleration of 9rad/s^2. What is the moment of inertia for the cylinder?
10.985 kg*m^2
work done by you * .57=35*g*5
solve.
Torque= 13*sin20*296
Torque= I * angular acceleration
use this to solve the third.
