Question

calculate the modulus of rigidity and bulk modules of a cylindrical bar of diameter 25 mm and length 1.6m if the longitude strain in a bar during tensile test is four times the lateral strain. Also find the change in volume when the bar is subjected to hydrostatic pressure of 100 mpa consider E=1*10^5

Answer 1

Answer:

calculate the modulus of rigidity and bulk modules of a cylindrical bar of diameter 25 mm and length 1.6m if the longitude strain in a bar during tensile test is four times the lateral strain. Also find the change in volume when the bar is subjected to hydrostatic pressure of 100 mpa consider E=1*10^5

mpa

Explanation:

cylindrical bar of 20 mm diameter and 1m length is subjected to a tensile test. Its longitudinal strain is 4 times that of its lateral strain. If the modulus of elasticity is 2 x 105 N/mm2 ,then its modulus of rigidity will be

Answer

8x106 N/mm2

8x105 N/mm2
