## Homework Statement:

- There is a wooden beam with given size. We put 1kg in the middle point of beam. Question is how much will the middle point lower itself? Young modulus is given.

## Relevant Equations:

- F/S = E.ε

I tried to use F/S = E.ε to find the new length after deformation and than use pytagoras theorem in right angled triangle to find how much did the middle point lower.

But it was said to me that my method is wrong and that there exists some formula to solve it. Can you please tell me where could I possibly find the formula?
