Question

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