The forces acting on a pin a truss joint are shown. The diameter of the pin is 20 mm. Determine the maximum transverse shear stress in the pin.

Solution

maximum transverse shear stress will be due to 40 kN

shear force = 40000 N

shear area = 3.141 x (0.01)^2

shear stress = shear force/shear area = 40000/(3.141 x 0.01^2)= 1.273 x 10^8 N/m^2
