Three elastic wires `PQ, PR` and `PS` support a body `P` of mass `M`, as shown in figure. The wires are of the some material and cross sectional area, the middle one being vertical. Find the loads by each wire.

Three vertical wires, I,II and III are supporting a block of mass M in horizontal positon. The wires are to equal length and cross-sectional area. It is given that Young's modulus of wire II, Y_(2) = Y_(3) (Yong's modulus of wire III ). The wire I and III and attached at extreme ends of the block.

P and Q are two wires of same length and different cross sectional areas and made of same material. Name the property which is same for both the wires.

A block of mass M is suspended from a wire of length L, area of cross-section A and Young's modulus Y. The elastic potential energy stored in the wire is

A block of mass M is suspended from a wire of length L, area of cross-section A and Young's modulus Y. The elastic potential energy stored in the wire is

A wire of length L and cross section A hung from a rigid support is loaded with a mass M The elongation produced is

If the resistance of wire A is three times the resistance of wire B and the two wires have the same length, compare their cross sectional areas. The two wires are made of the same material.
