1.For the problem given in the table, the specifications for the press fit of two cylinders are given in the original problem from Chap. 3. If both cylinders are hot-rolled AISI 1040 steel, determine the minimum factor of safety for the outer cylinder based on the distortion-energy theory.

2. A plate 100 mm wide, 200 mm long, and 12 mm thick is loaded in tension in the direction of the length. The plate contains a crack as shown in Fig. 5–26 with the crack length of 16 mm. The

material is steel with
KIc
= 80 MPa ・ √ m, and
Sy
= 950 MPa. Determine the maximum possible load that can be applied before the plate (a) yields, and (b) has uncontrollable crack growth.
