c.
11.31Mpa



d.
14.14MPa​

Answer 1

Answer:

D. 14.14mpa I think

If this is wrong sorry

Answer 2

Answer:

The correct answer is option (B).

conclusion:

use the formula,

Stress = $\frac{F}{A}$

Explanation:

A solid circular column of diameter 150mm carries a verticle load of 50kN at the outer edge of the column.

Diameter,

d = $\frac{15}{100}$

  = 0.15m

Force,

F = 50000N

r denoted as a radius of a cross-section.

A denoted as an area of cross-section.

By the formula,

r = $\frac{d}{2}$

 = $\frac{0.15}{2}$

 = 0.075m

By the formula,

Stress = $\frac{F}{A}$

         = $\frac{50000}{\pi} \times0.075^{2}$

         = 2830856.33N/$m^{2}$

         = 2.83MPa

So, the value of maximum stress is equal to 2.83MPa.
