Determine the reactions of simply supported beam to both a concentrated and uniform load.
A beam with a span of 21 ft is simply supported at the left-hand end and fixed at the right-hand end.
It carries a uniform load of 800 plf, which includes its own weight, over its entire span and a concentrated load of 12,000 lb located 7 ft from the left-hand end.
The total bending moment at the fixed end is equal to -81,400 ft-lb.
What is the reaction at the simple support?
What is the reaction at the fixed support?
