Imagine a rod made of a material of
youngs modulus **Y** and
length **l**,
area of cross section **A** ,
in Space far away from all gravitational fields

It is subject to 2 forces one **40N** and other **10N** acting on opposite faces in opposite directions as shown,

Find the net elongation of rod

If answer is **a**

find **100a**

**NOTE**

1) Any one can solve using calculus, try to do it **without** using calculus

2) Remembering a result or formula and solving it is **not** the same as a new method, in short- **Try to Avoid using calculus based results for this problem**

**-DETAILS AND ASSUMPTIONS**

1) L=1

2) A=5

3) Y=5
