Chapter 1, Problem 9P

A cylindrical part of diameter d is loaded by an axial force P. This causes a stress of P/A. where A = πd2/4. If the load is known with an uncertainty of ±10 percent, the diameter is known within ±5 percent (tolerances), and the stress that causes failure (strength) is known within ±15 percent, determine the minimum design factor that will guarantee that the part will not fail.

Prob # 1.A round bar made from SAE 1025 low Carbon steel is to support a direct tension load of 50,000 lbs. Using a factor of safety of 4, and assuming that the stress concentration factor, k = 1, What is the suitable standard diameter. Yield stress is 40,000 psi. a. 3 ½ inch          b. 2 ¼ inch c. 2 9/16 inch                                                          d. 1 ½ inch
The load on a helical spring is 1282 lb and the corresponding deflection is to be 3.4 inches. Rigidity modulus is 11 x 106 psi and the maximum intensity of safe torsional stress is 60,000 psi. If the wire diameter and the mean diameter are 0.5 in. and 3 in., respectively. Determine the number of active coils. Don't round your answer to preferred size. Round your answer to 4 significant figures
Determine the width and thickness of the leaves (in mm) of a leaf spring using the following specifications: Total load = 140 kN; Number of springs supporting the load = 4; Maximum number of leaves = 10; Span of the spring = 1000 mm; Permissible deflection = 80 mm; Modulus of elasticity, E = 200 kN/mm2; and allowable stress in spring material is 600 MPa.
