The down arm EA is made from 1.5" square solid steel with an allowable normal stress of 18 ksi. The center of E ID 4 ft roller E to the center of section DC is 1.25'. 1.5 in.- B 1.5 in. 5.5 ft A

The L-shaped member ABC is supported by a socket (3D pin) at A and the three cables CD, BD and BE. With the indicated load of 2.4 kN at F, find the tensions in the three cables. 1.26 m D 1.28 m 0.72 m F E 0.63 m 0.63 m В 0.96 m 2.4 kN

The boom AC is a 4-in. square steel tube with a wall thickness of 0.25 in. The boom is supported by the O.63-in .-diameter pin at A, and the 0.3-in.-diameter cable BC. Neglecting the weight of the boom, determine the shear stress in the pin (in psi) if P = 5012 Ib. Round off the final answer to two decimal places. 0007 P.png ... 70 4 in 3.5 in. 30 0.5-in dia.

For the bracket and loading shown in the figure, determine the smallest value of the distance a for which the magnitude of the reaction at B does not exceed 850 N. (Round the final answer to one decimal place.) a B 300 N 240 mm

Each of the three rolled-steel beams shown (numbered 1, 2, and 3) is to carry a 64-kip load uniformly distributed over the beam. Each of these beams has a 12-ft span and is to be supported by the two 24-ft rolled-steel girders AC and BD. The allowable normal stress for the steel used is 22.5 ksi. Determine the section modulus for each girder and select the most economical W shape for the two girders using the table given below. (Round the final answer to one decimal place.)

6) The assembly consists of two posts AB and CD made from material 1, having a modulus of elasticity E, and each cross-sectional area A₁, and a central post EF made from material 2, having a modulus of elasticity E2 and each cross-sectional area A₂. If the posts AB and CD are to be replaced by those having a material 2, determine the required cross-sectional area of these new posts so that both assemblies deform the same amount when loaded. ↓ B d E F d L D
