b. A draw bar between a tractor and a trailer is made from a length of steel with a rectangular cross-section 100 mm by 12 mm. The load is transmitted to the bar via a pin through a 25 mm diameter hole at each end as shown in Fig. 5b. x| and i. ii. 100 O25 x Y Y Fig. 5b If the load P in the bar is 100 kN, determine the following: The stress at the section X-X, shown in Fig. 5b. The stress at the section Y-Y, shown in Fig. 5b. ort ratelic Beam

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.

An annular washer distributes the load P applied to a steel rod to a timber support. The rod's diameter is 22 mm, and the washer's inner diameter is 25 mm, which is larger than the hole's permissible outer diameter. Knowing that the axial normal stress in the steel rod is 35 MPa and the average bearing stress between the washer and the timber must not exceed 5 MPa, examine the smallest allowed outer diameter, d, of the washer. %3D %3D +22 mm P Figure 4

Two aluminum plates, each having a width of b = 8.0 in. and a thickness of t = 0.750 in., are welded together as shown. Assume a = 4.0 in. For a load of P = 75 kips, determine (a) the normal stress that acts perpendicular to the weld and (b) the magnitude of the shear stress that acts parallel to the weld. Answer: O= P T = 1 i 1 ksi ksi b P
