If F is the force applied to an elastic bar to produce an extension of `Deltal`. Then, the energy lost in the process is

What does a constant force applied on a body produce?

When a load W is hung from a wire, it extends by Deltal . The heat produced in the process is

When a load W is hung from a wire, it extends by Deltal . The heat produced in the process is

A wire of length L and radius r is fixed at one end and a force F applied to the other end produces an extension l. the extension produced in another wire of same material of length 2L and radius 2r by a force 2F is

If overset rarr F is the force applied by the agent to produce a velocity overset rarr v in a body,then power supplied by the agent is :

When a force is applied at one end of an elastic wire, it produce a strain E in the wire. If Y is the Young's modulus of the material of the wire, the amount of energy stored per unit volume of the wire is given by
