The block of wood glued together as shown is subjected to a compressive force of P=34 kN. Determine the average shear stress (in MPa) developed in the wood fibers that are oriented along the glued joint at 44° with the axis of the block. Dimension of block is given as a-53 mm, b=52mm. P Do not include units in final answer. Answer in 3 decimal places. P b a

Two wood boards, each 18 mm thick, are joined by the glued finger joint shown. The finger joint will fail when the average shear stress in the glue reaches 1080 kPa. Determine the shortest allowable length d of the cuts if the joint is to withstand an axial load of P = 4.2 kN. Use a = 18 mm and b = 144 mm. d Glue b P P Answer: d = i mm

Required information For the concrete beam shown, the modulus of elasticity is 25 GPa for the concrete and 200 GPa for the steel. Take b=218 mm and d = 450 mm. Use an allowable stress of 12.5 MPa for the concrete and 140 MPa for the steel. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Using the area of steel calculated in part a, determine the largest allowable bending moment. The largest allowable bending moment is 96.06 kN-m.
