Q1: Knowing that the bracket AB has a uniform thickness of 5/8 in., determine the combined normal stresses at point K. 3 kips 30° A - 5 in.- K. 2 in. B 2.5 in

Determine the location of the shear center for the following section. Determine the shear stress at point A, if a 20 kN (downwards) shear load is applied at the shear center. Given: h1 = 25 mm h = 100 mm b = 50 mm Thickness = 4 mm. V ke- A |▬▬b▬|| h₁

. Problem 4: The lap joint is connected by 3 20mm - diameter rivets. Assuming that theload P = 50 KN is equally distributed among the 3 rivets, find-The shear stress in each rivet. - The bearing stress between rivet and plate. - The tensile stress in each plate.

The circular shaft shown is subjected to an axial force P at its free end and a compressive force of 50 kips at point B. Note that the shaft is hollow between points A and B. The allowable normal tension stress is 22 ksi, the modulus of elasticity is 29,000 ksi, and the maximum allowable elongation is 0.04 in. Determine the maximum allowable value of P in kips. -0.75 in A B C 50 kips 3 in 20 in 30 in
