### SOLVED:(a) What minimum force F is needed to lift…

So to consider the minimum of force needed to lift the piano, we can consider when it's already in motion but not accelerating, because then all we would need, ah to just keep it being lifted and some constant speed. So we know that we can draw free body diagram. So we have the force of gravity going straight downward, which is empty on the piano.

### calculating the minimum force needed to lift a rigid ...

So F = (200 lbs * 80 inches) / (2 * D inches) If D is say, 20 inches then F = 400 lbs. Solving this, I get 400 lbs of force needed if the actuator is connected at 20 inches from the camper (fulcrum). To have some wiggle room I will connect it slightly further out, say 24 inches, thus requiring 333 lbs of force.

Using this pulley system, what is the minimum input force needed to lift a piano weighing 1,595 N? Explanation: In a system with one moveable pulley, the input distance (distance the rope is pulled) is twice the output distance (din=2⋅dout). Because the system is 90% efficient, that means only 90% of the input work is converted to useful ...
