Elastic Moduli

The increase in pressure required to decrease the 200 L volume of a liquid by 0.004% (in kPa) is (Bulk modulus of the liquid = 2100 MPa)

A metal rod of length ????and cross-sectional area ????is heated through . What is the force required to prevent the expansion of the rod lengthwise ? [Y = Young's modulus of the material of rod , = coefficient of linear expansion]

The increase in energy of a metal bar of length 'L' and cross-sectional area 'A' when compressed with a load 'M' along its length is (Y = Young�s modulus of the material of metal bar)
