178 CHAPTER 2 Axially Loaded Members Stresses on Inclined Sections Problem 2.6-1 A steel bar of rectangular cross section (1.5 in. 2.0 in.) carries a tensile load P (see figure). The allow- able stresses in tension and shear are 14,500 psi and 7,100 psi, respectively. Determine the maximum permissible load P max . N UMERICAL DATA A 3 in 2 a 14500 psi a 7100 psi M AXIMUM LOAD - tension P max1 a A P max1 43500 lbs M AXIMUM LOAD - shear P max2 2 a A P max2 42,600 lbs Because allow is less than one-half of allow , the shear stress governs.
