Answer 2

$\large{ \underline{ \underline{ \sf{ \color{cyan}{REQUIRED- ANSWER:-}{} }{} }{} }{} }{}$

We Are Required to calculate the stress of steel rod.

It is given that,

• Radius = 10mm
• Length = 1.0m
• Force = 100KN

$\large{ \underline{ \underline{ \sf{ \color{lime}{TO \: FIND:-}{} }{} }{} }{} }{}$

• Calculate it's stress

$\large{ \underline{ \underline{ \sf{ \color{lime}{SOLUTION-}{} }{} }{} }{} }{}$

From the Basic Understanding of the question,The formula of stress can be equated and stress can be solved.

$\large{ \underline{ \underline{ \sf{ \color{yellow}{STRESS = :- \frac{F}{A} = \frac{F}{\pi {r}^{2} } }{} }{} }{} }{} }{}$

Let us substitute the Values,we get

$\sf{ \rightarrow{ \frac{100 \times {10}^{3} }{3.14 \times {10}^{2} } }{} }{} \\ \\ \sf{ \rightarrow{ \red{3.14 \times {10}^{8} {nm}^{2} }{} }{} }{}$

Hence Stress = 3.14 × 10⁸N/m²
