Suppose you place a 30kg weight 50cm from the pivot where should the following forces be applied to lift the load

Question

a)a 100N force
b)a 150N force

2)how far will the load in question 1 be lifted if:
a)the 100N force moves downwards
b)the 150N force moveddownwards 1m

Answer 1

1a. F2*d2 = F1*d1
100*d2 = 300*0.5 = 150
d2 = 1.5 m.

1b. 150*d2 = 300*0.5 = 150
d2 = 1.0 m.
