Question

explain mechanical equilibrium........​

Answer 1

Definition:

A system is said to be in mechanical equilibrium when no mechanical work is done by one part of the system on any other part of the system.

Explanation:

Question : Explain Mechanical quilibrium.

Main Definition : A body is said to be in mechanical equilibrium if the total force acting upon it is zero and the total torque acting on it is zero. As the net force and torque on a body are zero, it will continue to move in a straight line with constant velocity and rotate with a constant angular velocity. If the velocity of a body in mechanical equilibrium is zero, then it will remain at rest.

Answer 2

Answer:

A system is said to be in mechanical equilibrium

when there are no unbalanced forces within the

system and between the system and its surround-

ings.

OR

A system is said to be in mechanical equilibrium

when the pressure in the system is the same

throughout and does not change with time.

Note: The constituents of a system, atoms, molecules,

ions, etc, are never at rest. Within a system, even in the

condition of equilibrium, statistical fluctuations do occur,

but the time of observation is usually very large so that

these fluctuations can be ignored.]
