Problem: The two objects in the figure below are balanced on the pivot, with m = 1.7 kg. What is distance d?

FREE Expert Solution

A Moment (torque) is the product of Force and Distance.

τ=F·r sin θ 

F=mg

Let clockwise torque be positive and counter-clockwise torque be negative.

The system is in equilibrium. Therefore, the sum torque should be zero

Στ=0Στcw-Στccw=0
