One end of a slack wire (Young's modulus Y, length L and cross-section area A) is clamped to rigid wall and the other end to a block (mass m) which rests on a smooth horizontal plane. The block is set in motion with a speed `v`. What is the maximum distance the block will travel after the wire becomes taut ?

One end of spring of force constant k is fixed to a vertical wall and the other to a block of mass m resting on a smooth horizontal surface. There is another wall at a distance, x_(0) from the block . The spring is then compressed by 2x_(0) and released. The time taken by the block to strike the other wall is

Y is the Young's modulus of the material of a wire of length L and cross-sectional area A. It is stretched through a length l. What is the force constant of the wire?

Young's modulus for a wire of length L and area of cross-section A is Y. What will be Young's Modulus for wire of same material, but half its original length and double its area?

Young's modulus for a wire of length L and area of cross-section A is Y. What will be Young's Modulus for wire of same material, but half its original length and double its area?

The left end of the spring tied to a wall and at the right end is attached to a block of mass m , which is placed on a frictionless ground. The force F displaces the block by distance x where it is exactly balanced by the spring force. What is the maximum speed of the block in the ensuing motion after the force F is removed?

Rigidity modulus of steel is eta and its Young's modulus is Y. A piece of steel of cross sectional area A is chaged into a wire of length L and area (A)/(10) then :

A wire of length l and cross-sectional are A is suspended at one of its ends from a ceiling. What will be its strain energy due to its own weight, if the density and Young's modulus of the material of the wire be d and Y?
