(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

In a pole with dimension lo=5m and section S=20 cm square acts the force of F=20Kn vertically

downwards . How long will it go downwards, ---- thus delta l is needed

2. Relevant equations

I have delta l /lo =1/ EY *F/S

3. The attempt at a solution

I know the solution is giving me only delta l = 0.25 mm

how do i get delta l from above formula and what about EY which isnt needed ?

Could this be correct delta l = lo/ey * F/s ?
