Question

definition of mechanical equilibrium​

Answer 1

A standard definition of mechanical equilibrium for a particle is:

The necessary and sufficient conditions for a particle to be in mechanical equilibrium is that the net force acting upon the particle is zero

♣ MECHANICAL EQUILIBRIUM

✍️ In thermodynamics, a mechanical equilibrium is defined as a uniform pressure (for a fluid).

✍️ In classical mechanics, equilibrium is defined by sum of external forces equals to zero.

✍️ The link between the two is that no external forces work at an equilibriumNet

♣ CONDITION REQUIRED

✍️ Torque Must Be Zero.

✍️ The second conditionnecessary to achieve equilibrium involves avoiding accelerated rotation (maintaining a constant angular velocity ).

✍️ A rotating body or system can be in equilibrium if its rate of rotation is constant and remains unchanged by the forces acting on it.

♣ TYPES OF MECHANICAL EQUILIBRIUM

♦There are two kinds of mechanical equilibrium:

✍️ Any object which is in static equilibrium has zero net force acting on it and is at rest.

✍️ Any object which is in dynamic equilibriumhas zero net force acting on it and is moving at a constant velocity.
