1.5 in. 2 in. 1 in. 20 lb Probs. 1-62/63 *1-64. The triangular blocks are glued along each side of the joint. A C-clamp placed between two of the blocks is used to draw the joint tight. If the glue can withstand a maximum average shear stress of 800 kPa, determine the maximum allowable clamping force F. 1-65. The triangular blocks are glued along each side of the joint. A C-clamp placed between two of the blocks is used to draw the joint tight. If the clamping force is 900 N, determine the average shear stress developed in the glued shear plane.
