Q. For a cantilever beam with a point load at the free end, what is the deflection at the free end?
A.
WL^3/(3EI)
B.
WL^3/(12EI)
C.
WL^2/(2EI)
D.
WL^4/(8EI)
Solution
The deflection (δ) at the free end of a cantilever beam with a point load (W) at the end is given by δ = WL^3/(3EI), where E is the modulus of elasticity and I is the moment of inertia.
