τ = T * r / J

5.1 What is the difference between stiffness and rigidity? FULL Solution Manual Of Machine Design By Rs Khurmi Gupta

Solution: Stiffness is the resistance of a component to deformation under load, while rigidity is the resistance of a component to deformation under load in a specific direction. τ = T * r / J 5

Solution: Using Hooke's law, we can calculate the strain as follows: F = 10

where n = 4, F = 10,000 N, and D = 100 mm

ΔL = (10,000 N * 100 mm) / (π * (20 mm)^2 / 4 * 200,000,000 Pa) = 0.0796 mm
