the two objects in the figure(figure 1) are balanced on the pivot.

The two objects in the figure below are balanced on the pivot, with m = 1.3 kg. What is the distance of d?

the two objects in the figure(figure 1) are balanced on the pivot.

Answer:

d = Xcm = ΣMom/Σmass = (4*1.5+1.3*1)/(4+1.3) = 1.377 m

Sum of torques about pivot = 0/g = 0:

(d-1)1.3 = (2-0.5 – d)4

d = 1.38 m answer
