Chapter 1, Problem 12P

A solid circular rod of diameter d undergoes a bending moment M = 1000 Ibf · in inducing a stress σ = 32M/(πd3). Using a material strength of 25 kpsi and a design factor of 2.5. determine the minimum diameter of the rod. Using Table A-17 select a preferred fractional diameter and determine the resulting factor of safety.

A solid circular rod of diameter d undergoes a bending moment M = 113 Nm inducing a stress σ = 16M/ (πd3). Using a material strength of 172.4 MN/m2 and a design factor of 2.5, determine the minimum diameter of the rod. Using Table 1, select a preferred fractional diameter and determine the resulting factor of safety
A steel rod is subjected to a reversed axial load of 180 kN. Find the diameter of the rod for a factor of safety of 2. Neglect column action. The material has an ultimate tensile strength of 1070 MPa and yield strength of 910 MPa. The endurance limit in reversed bending may be assumed to be one-half of the ultimate tensile strength. Other correction factors may be taken as follows: For axial loading (Ka) = 0.7; For machined surface (Ksur) = 0.8 ; For size (Ksz) = 0.85 ; For stress concentration(Kf)= 1.0.3.
Find the equivalent stresses at Points 1 and 2 of the element with given geometry and loading conditions according to the Maximum shear stress hypothesis and the Maximum strain energy hypothesis. Shaft diameter: 20 mm, Shaft Length 120 mm, F1 = 750N, F2 = 3000N, Mb = 2400 N.mm. Steel if St37 and Safety coefficient is 2 If taken, will this stick work safely under these operating conditions? (Yield of given steel Strength 225 Mpa, Tensile strength 370 Mpa)
