Three cables shown in the figure are used to carry a load P of 100 kips. All cables are 1.75" in diameter and all are 6' long. Cables A and C are made of an aluminum alloy, with modulus E = 10,600 kpsi and cable B is made of a structural steel whose E = 28,000 kpsi
If there is a strain gage in cable A whose EA = 750 M in / in
Determine:
A) Length change in each of the cables
B) The force P
