An Indian rubber cord L metre long and area of cross-section A `"metre"^(2)` is suspended vertically. Density of rubber is D `"kg/metre"^(2)`. If the wire extends by `l` metre under its own weight, then extension `l` is

An indian ruber cord L meter long and area of cross-secion A metre is suspended vertically. Density of rubber is rho kg/ "metre"^(3) and Young's modulus of rubber is Y newton/ "metre"^(2) . IF the cord extends by l metre under its own. Weight, then extension l is

A rubber cord of density d, Young's modulus Y and length L is suspended vertically . If the cord extends by a length 0.5 L under its own weight , then L is

A rubber cord of density d, Young's modulus Y and length L is suspended vertically . If the cord extends by a length 0.5 L under its own weight , then L is

Why should the area of cross section of metre bridge wire be uniform?

wire of length I has a ear mass density lambda and area of cross-section A and the Young's modulus y is suspended vertically from rigid support. The extension produced in wire due to its own weight

wire of length I has a ear mass density lambda and area of cross-section A and the Young's modulus y is suspended vertically from rigid support. The extension produced in wire due to its own weight

A wire of natural length l , young's modulus Y and area of cross-section A is extended by x . Then, the energy stored in the wire is given by
