Textbook Question
Chapter 3, Problem 3.25QP
A No. 10 steel rebar is tested in tension. By monitoring the load reading of the testing machine, it was found that the specimen yielded at a load of 41,600 lb and fractured at 48,300 lb.
- 1. Determine the tensile stresses at yield and at fracture.
- 2. Estimate how much increase in length would occur at 70% of the yield stress in a 2-in. gauge length.

A mercury U-tube manometer is used to measure the pressure drop across an orifice
in pipe. If the liquid that flowing through the orifice is brine of sp.gr. 1.26 and
upstream pressure is 2 psig and the downstream pressure is (10 in Hg) vacuum, find
the reading of manometer.
Ans. R=394 mm Hg
