Textbook Question
Chapter P, Problem 14PS
In mathematics, is is important to read the directions before attempting to work any problems. You are NOT expected to able to work any problems. You are NOT expected to be able to work Problems 11-60 at this time. You ARE expected to be able to work those problems AFTER reading this text. So for now, just place each assigned question in one of the following categories:
Yes. I know how to start this problem.
No. I don’t think I know how to start this problem.
Hopeful. If someone shows me how to proceed, I think I could answer this question.
Hopeless. I don’t think I’ll ever be able to answer this question.

5.15 The ends of the laminated-wood roof arch shown are
tied together with a horizontal steel rod 90 feet, "10 inches"
long, which must withstand a total load of 60 k. Two turn-
buckles are used. All threaded rod ends are upset.
a. Determine the required diameter D of the rod if
the maximum allowable stress is 20 ksi.
b. If the unstressed length of the rod is 90 feet,
"10 inches" and there are four threads per inch
on the upset ends, how many turns of one
turnbuckle will bring it back to its unstressed
length after it has elongated under full allowable
tensile stress? E = 29 × 103 ksi.
