A vertical metal cylinder of radius $2 c m$ and length $2 m$ is fixed at the lower end and a load of $100 k g$ is put on it. Find (a) the stress (b) the strain and (c) the compression of the cylinder. Young modulus of the metal = $2 \times 10^{11} N m^{- 2}$

Solution

Stress $= \frac{F o r c e}{A r e a}$ = $\frac{1000}{3.14 \times 0.02 \times 0.02} = 0.1273 N / m^{2}$
for strain there should be young's modulus constant proided $.$
And hence the compersion $.$
So $,$ letting the young modulus be $Y .$
Strain $\frac{S t r e s s}{Y} = \frac{0.1273}{Y} .$
