Modulus of rigidity and Poisson’s ratio are 0.4 × 10⁵ MPa and 0.34 respectively. The Young’s modulus of elasticity is

The bending moment distribution in a beam is a function of distance x and it is given by M = (5x² + 20x - 7) Nm. Find the shear stress at x = 2m if the shearing area is 2 mm².

A steel rod 3 m long with a cross sectional area of 250 mm² is stretched between two fixed points. The tensile force is 12000 N at 40°C. Using E = 200 × 10³ N/mm² and α = 11.7 × 10^-6 mm/mm°C.

Calculate the temperature at which the tensile stress in the bar will be 100 N/mm².

A thin cylindrical shell 2.5 m long and a diameter of 1.25 m has a thickness of 20 mm. Then the change in dimension of diameter of the shell which is subjected to measure of 1.5 MPa is ______mm (Take Young's Modulus E = 200 GPa, and Poisson's Ratio μ = 0.3)

Direct stresses of 120 N/mm² (tensile) and 90 N/mm² (compressive) exist on two perpendicular planes at a certain point in a body. They are also accompanied by shear stresses on the planes. The greater principal stress at the point due to these is 150 N/mm². The shear stress on these planes is equal to
