The anchor opposite is made of Cr-Ni steel. Thereelastic limit is 520 Mpa. What should be the minimum diameter inanchor shear if the load F is 50kN? Consider a safety factor of 2.Please note that the safety factor is applied tothe elastic limit.
Question 1 A composite beam ıs constructed from a wood beam (75 mm wide, by 150 mm hıgh) and a steel plate 75 mm wide The wood and the steel are securely fastened to act as a single beam Calculate the required thickness of the steel plate if the allowable compressıve stress ın 11 the wood is 14 MPa and allowable tensıle stress in the steel plate is 110 MPa GIven that the composite beam is subjected 1 2 to a positive bendıng moment M 8.5 kN.m, calculate maximum bending stress in the wood Assume that Ew 11 GPa and Eg = 200 GPa.
A plain concrete wall (i.e., a wall with no steel reinforcement) rests on a secure foundation and serves as a small dam on a creek (see figure). The height of the wall is h = 6.0 ft and the thickness of the wall is t = 1.0 ft. Determine the maximum tensile and compressive stresses o*!and trt, respectively, at the base of the wall when the water level reaches the top {d = h). Assume plain concrete has weight density ye= 145 lb/ft . Determine the maximum permissible depth dnuxof the water if there is to be no tension in the concrete.
very urgent and quickk
