Question

the Young's modules for a given material is 100 kn/mm and it's modules of rigidity is 40 kn/mm determine it's bulk and also it's lateral contraction of the diameter 50 mm and length 2 m and extension is 2 mm​

Answer 1

Load p =45 KN = 45 x 103 N

Young’s modulus E = 200 KN /mm2

Length of the rod, l = 500 mm

Diameter of the rod = 20 mm
