A beam with a half-circular cross-section with radius R = 1.6 in is subjected to a maximum positive bending moment of 27100 lb*in about a horizontal axis. Determine the maximum tensile and compressive flexural stress in the beam. R Denote a tensile stress with a positive number, and a compressive stress with a negative number. mazc = psi psi A beam with a half-circular cross-section with radius R = 1.6 in is subjected to a maximum positive bending moment of 27100 lb*in about a horizontal axis.
