State the conditions for equilibrium. Under which condition(s) is a body not static but still in equilibrium?
here,
For a body to be in equilibrium
the net force on the body must be ZERO
the net torque on the body must be ZERO
when a body is moving at constant velocity
the body is not static , but it can be in equilibrium
when (the net force on the body must be ZERO
the net torque on the body must be ZERO
)
ANSWER :
Conditions for equilibrium :
∑H = sum of horizontal components of forces = 0
∑V = sum of vertical of components of forces = 0
∑M = sum of moments = 0
When the body is in motion it is under action of net force it is not static. However it can be in dynamic equilibrium when it keeps moving and does not fall.
