## Homework Statement

If w = 74 kN/m , determine the absolute maximum bending stress in the beam in MPa.

## Homework Equations

I'm not too sure how to go about my calculations. Please help!

## The Attempt at a Solution

I = [(1/12)*(200*256^3)] - [(1/12)*(192*250^3)] = 29.62*10^6

F = 74*24*1000? [/B]
