Question

A man holds a rope which is draped over a pulley and attaches to a 65 kg mass on a 30° ramp. The rope pulls the mass back up the ramp with a force parallel to the slope of the ramp. Assuming there is no friction, what is the force of tension in the rope if the mass remains stationary?

Answer 1

$$F=mg\sin{30}\\F=(65)(9.8)\sin{30}=319\ N$$
