Question

Part A - Moment about the x axis at A Learning Goal: To determine the state of stress in a solid rod using the principle of superposition. A solid rod has a diameter of e = 60 mm and is subjected to the loading shown. Let a = 200 mm, b = 220 mm c = 340 mm, d = 230 mm, and P = 4.0 kN. Take point A to be at the top of the circular cross-section. (Figure 1) As shown (Figure 2), a cut was made at A to determine the resultant internal loadings. Determine the moment about the x axis, M, Express your answer to three significant figures and include the appropriate units.

Determine the moment about the z axis, M. Express your answer to three significant figures and include the appropriate units. View Available Hint(s) 2

Answer 1

Answer (A) moment about x-axis at a is given by Mx= = Pxd = (4x103)0.230) Mx = 920 Nom Aus (B) Moment about z-axis at A is given by Mz=-PxC =-(4x10")(0.340) Any MzE-1360 N-m (C) Stress due to normal force is given by = a = А ce) 3 4X10 3.14.603 =1.415 Mpal Aug A (0) Stress due bending moment is given by MxZ (920 x103)( 62 ) 609 = IA 64 Cat = 43.406 Mpal Any Good Luck Please like
