A shaft with 15 mm diameter is fixed as shown below. The shaft is made from AISI 1006 cold drawn steel (280 MPa). The (a) Draw the stress elements at point A (top of shaft) and B (side of shaft), indicating the magnitude and directions of the stresses. applied loading is as follows: F = 0.55 kN, P = 4 kN, T = 25 Nm. (b) Find the safety factor at point A and B using both MSS and DE theory. -100 mm A 15-mm D.

The pin-connected assembly consists of aluminum rods (1) and (2) and steel rod (3). The aluminum rods each have a diameter of 11 mm and an elastic modulus of E = 78 GPa. The steel rod has a diameter of 16 mm and an elastic modulus of E = 200 GPa. Assumea = 4.1 m, b= 1.2 m, and c= 1.2 m. What is the magnitude of load P that is necessary to displace point A 12 mm to the left? a (1) (3) A B (2) Answer: P = i kN
