HW #04-1
A tension test was performed on a steel specimen having an original
diameter of 0.498 inches and a gauge length of 3.00 inches. The load
and elongation data from the test is listed in the table. Plot the stressstrain diagram and determine the mod

HW #05-1
The three legs of the structure between lines A and B are identical in size and are fixed
to a rigid support at A. Member BC is attached to the center of the connecting element
at B, and the three legs between AB are equidistant from the center o

HW #06-1
The column is composed of concrete fully bonded to 8 internal steel reinforcing rods.
The column has a square cross section with 14-inch side length. The bars each have a
diameter of 1.128 inches. A compressive load of P = 800,000 lb is applied t
