## Homework Statement

Beam spans 40 feet, with uniform loading of 500 pound/feet and a point load of 4000 pound at mid span.

Support A is roller, support B is pin.

How to determine the maximum moment and maximum deflection due to the loads.

__Use Force method__

Since it is a Determinate structure, I am not very sure how to use the method.

## Homework Equations

Delta + f F = 0

find Delta

## The Attempt at a Solution

I suppose I need to add a virtual force of 1 pulling the structure down at mid span... so that it generates 2 virtual moments (m).

From the original structure, I can also get 2 real moments (M).

Then using the equations:

Delta = integration of m*M / EI ...

f = integration of m*m / EI

And then I will know deformation??
