8-27. The lap joint is connected together using a 30 mm diameter bolt. If the bolt is made from a material having a shear stress-strain diagram that is approximated as shown, determine the permanent shear strain in the shear plane of the bolt when the applied force P- 680 kN is removed. 7 (MPa) 525 350 (rad) 0.005 0.05

The d = 17-mm-diameter solid rod passes through a D = 22-mm-diameter hole in the support plate. When a load P is applied to the rod, the rod head rests on the support plate. The support plate has a thickness of b = 10 mm. The rod head has a diameter of a = 34 mm, and the head has a thickness of t = 8 mm. The shear stress in the rod head cannot exceed 145 MPa, the punching shear stress in the support plate cannot exceed 100 MPa, and the bearing stress between the rod head and the support plate cannot exceed 145 MPa. Determine the maximum value of Pmax that can be supported by the structure.

The beam has a square cross section and is made of wood having an allowable shear stress of Tallow= 1.4 ksi. If it is subjected to a shear of V= 1.5 kip, determine the smallest dimension a of its sides. Sketch the shear stress distribution acting across the beam's cross section. Hint: Construct the stress distribution in 2D similar to in-class examples, rather than isometrically similar to the textbook examples for clarity. V = 1.5 kip

The long bolt passes through the 70.4-mm-thick plate. If the force in the bolt shank is 9.5 KN, then the average shear stress (MPa) along the cylindrical area of the plate defined by the section lines a-a is: O a. 0.00 O b. 21.00 O c. 2.39 O d. 4.77 O e. 1.19 18 mm b b 8 mm Time left 0:45:52 a 7 mm YouTube The wood beam has an allowable shear stress of 15 MPa, the maximum shear force V (kN) that can be lind to the cross section is:
