The pulley below has a mechanical advantage of 3 and has a load of 300N assume an ideal pulley without friction losses, determine the following: a) what input force (input) do you apply to lift the load of 300 N? B) what is the tension in the 3 lines of the ropes of the pulley on the output side with the load as illustrated in the diagram? C) if the load is lifted to a height of 12 cm, how much rope is pulled on the input side d (in) in the diagram? D) how much work in joules (j) is required to lift the 300 N load 12 cm (0.12m)? E) how much power in watts (w) is required to lift the 300N load a distance of 0.12m in 20 seconds.
