Complete Question is attached below

Answer:


P=1124.2ibf

Step-by-step explanation:

From the question we are told that:

Diameter
d=1.2in

Allowable Normal stress
\sigma=27.5ksi=27.5 * 10^3 psi

Generally the equation for Bending Stress is mathematically given by


\phi= (32M)/( \pi d^3)


\phi= {32 * 4 P}{\pi * 1.2^3}


\phi=23.58 psi

Generally the equation for Direct Normal Stress is mathematically given by


\sigma'=(4P)/( \phi * 1.2^2)


\sigma'= 0.88P psi

Therefore

Total Normal stress


\sigma_T=23.58 + 0.88


\sigma_T=24.46P

Generally the equation for Allowable Stress is mathematically given by


\sigma=\sigma_T P


P=(\sigma)/(\sigma_T)


P=(27.5 * 10^3)/(24.46P)


P=1124.2ibf
