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
