Question

Design a simply supported, wide flange beam to support a uniform distributed lead of 5.000 lb/ft. The beam is 20 ft long and is A36 steel. Use the following constraints:

1. Maximum allowable bending stress = 24 ksi.

2. Maximum allowable shear stress = 18 ksi.

3. Maximum deflection = L/240

Note: You must select the size of the beam based on one of the above constraints then check the other constraints to be
