According to this, if we increase the stress so the area of section is decreased. So when stress is equal to working stress so the area becomes infinite.

Anyone please explain this.

D should be the correct answer.

Working stress means maximum so the area will be minimum.

Option D is correct.

Option D is correct I think.

Freely prismatic bar stress is equal zero. So area is infinite.

Consider S = stress.

Then partial derivative of stress with respect area.
dS/dA=pd(A power minus 1)/dA,
solve it,
A=p/0,
A= infinite.

I think area has to e infinite when stress is maximum in order to avoid unwanted situation.

Minumum is correct one.
