23.5 Consider the beam above to also be loaded by a uniformly distributed load of 20(lb)/(ft) downward and a tension load of 10,000lb. Compute the maximum normal stress in the beam for this loading condition. (Ans. sigma _(max)=40,903psi ) The cantilever beam below has a circular cross-section with a diameter of 4 inches and is subjected to a concentrated load and a torque as shown. Plot the value of the shear stress throughout the cross-section of the beam and determine the maximum shear stress within the cross-section.
