A propped cantilever beam of span L with a uniformly distributed load w per unit length has a prop reaction at the free end of:
Strength of MaterialsPropped Cantilever ReactionMEDIUM
Choose the correct answer
A
3wL/8
B
5wL/8
C
wL/2
D
wL/4
Correct Answer
A. 3wL/8
Why is this the answer?
Propped cantilever with UDL w: prop reaction R = 3wL/8 (at the simply supported end). Fixed end reaction = 5wL/8, fixed end moment = wL^2/8. This is a standard one-degree statically indeterminate beam solved by compatibility (deflection at prop = 0). Bending moment at fixed end = wL^2/8 (hogging).
