Question

Explain the principle of virtual work
​

Answer 1

Answer:

hey mate, here is your answer..

Explanation:

The principle of virtual work states that in equilibrium the virtual work of the forces applied to a system is zero. Newton's laws state that at equilibrium the applied forces are equal and opposite to the reaction, or constraint forces. This means the virtual work of the constraint forces must be zero as well.

hope it helps u frnd !
