What do you understand by mechanical equilibrium of a rigid body?
Asked by Topperlearning User | 11 Aug, 2014, 03:32: PM
answered-by-expert Expert Answer

For mechanical equilibrium of a rigid body, two conditions need to be satisfied:

1. Translational equilibrium: The net external force or the vector sum of all the external forces acting on the body must be zero.i.e 

Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.

2.Rotational equilibrium :The net external torque or the vector sum of all the torques acting on the body is zero.

i.e 

Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.

A uniform beam of length L meters and weight M kg supports two unequal masses each of mass m1 and m2 respectively, balanced at the opposite ends of the seesaw. Calculate the normal force N exerted on the beam by the support, and develop the equations for net force and net torque for the system using equilibrium conditions for a rigid body.
