8.13 An engineering member is to be made of an aluminum alloy. It is in the shape of a plate loaded in tension that may have a crack in one edge, as shown in Fig. 8.12(c). The dimensions are width b = 40 mm and thickness t = 4.0 mm, and the crack may be as long as a = 8.0 mm. The member must resist a tension force of P = 7.5 kN. (a) For a safety factor of...

2. (15 pts) A tension member made of 18-Ni maraging steel (air melted), (properties in table 8.1), has a length of 1200 mm, a width of 100 mm, and a thickness of 15 mm. It may have a through thickness edge crack that measures 15mm in length as shown in figure 8.12(c). What tension force P can be allowed for a safety factor against brittle fracture in stress (%) of 3.0?

Consider a member with a rectangular cross section subjected to
a compressive load P which is delivered through a rigid block on
the upper end of the member as illustrated below. The upper end of
the member is free to rotate about both axis directions, but is
constrained from lateral deflection in one of the directions by the
rigid guide plates illustrated. The lower end is hinged and this
allows rotations about one axis direction only. Assume the member
is...

Question 1 Shaft AB is supported at B by a roller support and at A by a pin support as well as a spline that prevents rotation around x axis. The diameter of the shaft is D. At cross section A-A there is a relief groove where the minimum diameter is d. Two loads, F, and one torsion moment, T, are acted on the shaft. The material of the shaft is aluminum 7075, Sy = 495 MPa. Also known: L=630...
