## Homework Statement

How do I find an expression for the deflection at midspan for a cantilever beam loaded with a uniformly distributed load?

## Homework Equations

[itex]\delta = \frac{Qx^2}{24EI}(6L^2-4Lx+x^2)[/itex]

## The Attempt at a Solution

My current answer is: [itex]\frac{49QL^4}{1280EI}[/itex], I think this is wrong. Putting [itex]x = \frac{L}{2}[/itex] in the elastic curve formula I get: [itex]\frac{17QL^4}{384EI}[/itex], I think this is the correct answer.
