Concept of Strain Energy

Science > Physics > Elasticity > Concept of Strain Energy In this article, we shall study, work done in stretching wire and the concept of strain energy. Work done in Stretching a Wire: Consider a wire of length ‘L’ and area of cross-section ‘A’ be fixed at one end and stretched by suspending a load […]

Stresses and Strains in Compound Wires

Science > Physics > Elasticity > Stresses and Strains in Compound Wires Problem – 1: For two wires of the same material, both the radii and lengths are in the ratio 1:2. What should be the ratio of stretching forces on the wires if equal extensions are to be produced in the two? Given: Ratio of […]

Numerical Problems on Poisson’s Ratio

Science > Physics > Elasticity > Numerical Problems on Poisson’s Ratio In this article, we shall study the concept of poisson’s ratio and numerical problems on it. The concept of this constant (Poisson,s ratio) was introduced by physicist Simeon Poisson. When a rod or wire is subjected to tensile stress, its length increases in the […]
