A 20-kg object is suspended from one end of a 30-kg wooden bean 3.0m long. Where should the bean be picked up so that it remains horizontal?
The Second Condition of Equilibrium was presented by Issac Newton. According to this condition, an object that is in equilibrium does not move along a straight line. Which means that the the sum of all forces applied on it is zero.
Also, the sum of all the rotational forces on the object is zero due to which the object does not rotate. Thus, the second condition of equilibrium states that the sum of all the torques on an object that is in equilibrium are zero.
