The equivalent load (f) acting on a simply supported beam element loaded with uniformly distributed load (p) over an element of length (l) is given by which of the following expressions?

• A. f=\([\frac{pl}{2},\frac{pl^2}{12},\frac{pl}{2},-\frac{pl^2}{12}]\)
• B. f=\([\frac{pl}{2},\frac{pl^2}{12},\frac{pl}{2},\frac{pl^2}{12}]\)
• C. f=\([\frac{pl}{2},-\frac{pl^2}{12},\frac{pl}{2},-\frac{pl^2}{12}]\)
• D. f=\([\frac{pl}{2},\frac{pl^2}{12},\frac{-pl}{2},-\frac{pl^2}{12}]\)
