Solution

Deflection = P1*L/(A1*E1) = P2*L/(A2*E2)

P1 = (A1*E1)/(A2*E2)*P2

Also, P1 + P2 = P

(A1*E1)/(A2*E2)*P2 + P2 = P

P2*[1 + A1*E1/(A2*E2)] = P

P2 = P / [1 + A1*E1/(A2*E2)]

Deflection = P / [1 + A1*E1/(A2*E2)] *L / (A2*E2)

Putting values, Deflection = P / [1 + (3.875/4)^2*(3/30)] * 48 / (3.14*4^2 *30*10^6)

= 2.911*10^-8 * P lbs
