## Homework Statement

1.What is the formula to calculate the bending moment of a beam subjected to UDL?

2.What is the formula to calculate the bending moment of a beam subjected to point load?

## Homework Equations

Bending moment (UDL) = WL^2/8 (Kg-mm or Kg-m)

Bending moment (point load) = Force x Distance ( This is actually for a horizontal beam with load acting is a point load) (Kg-mm or Kg-m)

What is the formula for bending moment of a vertical beam subjected to a point load and a UDL on the top of it (load applied axially)?

## The Attempt at a Solution

I come through several formulas, like (W * X)(X/2) when a UDL is acting over the cantilever beam. I am bit confused how do they arrive with these formulas and where should I use what?
