A wooden beam is fabricated from one 2 × 16 and two 2 × 10 dimension lumber boards to form the double-tee cross-section shown. The beam flange is fastened to the stem with nails. Each nail can safely transmit a force of 176 lb in direct shear. The allowable shear stress of the wood is 83 psi. Assume b1 = 16 in., b2 = 2 in., d1 = 2 in., d2 = 10 in.(b) What nail spacing s would be necessary to develop the full strength of the double-tee shape in shear? (Full strength means that the maximum horizontal shear stress in the double-tee shape equals the allowable shear stress of the wood.) [Answer: s = 1.17 in]

If length of the cut d = 30mm, determine the maximum average shearing stress. provide your answer in MPa with precision to two decimal points. P Answer: Glue 25 mm 200 mm P 25 mm
PLEASE ANSWER IT AS FAST AS YOU CAN A beam is made of four pieces of wood in the shape shown. The pieces are attached to each other using nails. The spacing between the nails on the top board (s') and the side board (s) are unknown. If it is known that the beam is under a vertical shear of 600 N and the nails have a maximum load of 100 N, determine the required nail spacing. Take the distance (a) as 1 cm, (b) as 2 cm and (c) as 1.5 cm. If glue was used instead of nails, would the shear flow change? Use number to justify your response. Please make sure the answer is correct 100% and be accurate in your answer
