Topic 5.6d - Problem Assignment 4 - Beam Stresses

For the loaded beams shown below, determine the support reactions, and then using the beam designated by the problem:
1.) Determine the maximum bending stress ( )at the location stated.
2.) Determine the shear stress ( ) at the location stated.

1. For a rectangular 2 in x 8 in beam, find at x = 3 ft, and at x = 3 ft, 2 inches above bottom of beam. (2250 psi.; 141 psi.)

2. For WT 8 x 32 beam, find at x = 9 ft, and at x = 9 ft, 4 inches above bottom of beam.(53,630 psi., 2160 psi.)

3. For W 8 x 40 beam, find at x = 10 ft, and at x = 10 ft, 3 inches above bottom of beam. (8113 psi., 0 psi.)

4. For WT 12 x 60 beam, find at x = 4 ft, and at x = 4 ft, 8 inches above bottom of beam. (23,467 psi.; 3092 psi.)

5. For W 10 x 60 beam, find at x = 9 ft, and at x = 9 ft, 4 inches above bottom of beam.(1000 psi.; 870 psi.)
