Question

First law of equilibrium

Answer 1

An object in static equilibrium has zero net force acting upon it.

The First Condition of Equilibrium is that the vector sum of all the forces acting on a body vanishes. This can be written as

F = F1+ F2+ F3+ F4+. . . = 0

Answer 2

for an object to be in equilibrium, it must be experiencing no acceleration. Both the net force and the net torque must be zero.
