A 36-ft simple beam that supports a service uniform dead load of 1.0 k/ft and a service concentrated live load of 25 k at midspan is laterally unbraced except at its ends and at the concentrated load at midspan. If the maximum permissible centerline deflection under service loads equal L/360 total load and L/1000 live load, select the most economical W section of 50 ksi steel, considering moment, shear and deflection. The beam self-weight is included in the uniform dead load. Use Cb = 1.0.
