Question

calculate the increasein energy of abrass bar of length area 1 cm sq. When compressed with a load 5 kg weight along its length young modulus of brass =1×10 to the power 11n/m sq. and G = 9.8​

Answer 1

Answer:

A brass rod of cross-sectional area

and length 0.2 m is compressed lengthwise by a weight of 5 kg. if young's modulus of elasticity of brass is

and

then increase in the energy of the rod will be
