Topic 5.6c - Problem Assignment 3 - Horizontal Shear Stresses

1. A 6’ long rectangular 2"x 6" beam is simply supported at its ends. It has a point load of 200 pounds at its midpoint. What is the maximum horizontal shear stress in the beam? (12.5 psi)

2. A 14’ long rectangular 2"x 10" beam has a distributed load of 50 pounds per foot. It is simply supported at its ends. Determine the maximum horizontal shear stress in the beam. (26.25 psi)

3. A 10’ long cantilever 4"x 4" beam has a 150 pound load at its extreme end. Find the maximum horizontal shear stress in the beam. (14.1 psi)

4. A 8’ long rectangular beam has point loads of 500 pounds at the 2’, 4’ and 6’ marks. The beam is simply supported at its ends. Determine the depth of beam if it is 2" wide and has maximum horizontal shear stress of 95 psi. (5.92")

5. Determine the maximum point load that can be suspended from the end of a 4’ long 4"x 4" cantilever beam. The maximum allowable horizontal shear stress for construction fir is 95 psi. (1013 lb)

6. Determine the maximum uniformly distributed load that can be carried by an 8’ long 2"x 10" beam which is simply supported at its ends. The allowable bending stress is 1500 psi. What is the maximum horizontal shear stress in the beam? (65 lb/ft, 19.5 psi)
