Q. No .1 A solid 20-mm-diameter shaft is subjected to an axial
load P. The shaft is made of aluminum [E = 70 GPa; v = 0.33].
A strain gage is mounted on the shaft at the orientation shown in
the figure below.
(a) If P = 18.5 kN, determine the strain reading that would be ex-
pected from the gage.
(b) If the gage indicates a strain value of ɛ = 950 µɛ, determine
the axial force P applied to the shaft.
