Reconsider the two composite columns and their cross-sections previously introduced in Question 2.Assume that these columns are subjected to the same sustained shortening displacement So_appliedat time to and maintained constant afterwards (see time axis below). This displacement So is assumedto produce a total strain ε at time to.64800timeProvide a qualitative description of the variation over time due to creep effects (do not considershrinkage effects in this question) of the following variables for each of the two columns considered(i.e. columns 1 and 2 introduced in Question 2):1) deformations in the concrete2) deformations in the steel3) stresses in the concrete4) stresses in the steelFor each of these variables (i.e. deformations in the concrete and steel, and stresses in the concreteand steel), comment as to which cross-section (i.e. cross-section A-A of column 1 or cross-section B-Bof column 2) is expected to exhibit higher deformations and stresses in the concrete and steel.

For silver at a tensile stress of 7 MPa and a temperature of 839C , there are two equally contributing creep mechanisms. What are they?
A tensile test was performed on a metal specimen having a circular cross section with a diameter 0. 510 inch. For each increment of load applied, the strain was directly determined by means of a strain gage attached to the specimen. The results are, shown in Table: 1.5.1. a. Prepare a table of stress and strain. b. Plot these data to obtain a stress-strain curve. Do not connect the data points; draw a best-fit straight line through them. c. Determine the modulus of elasticity as the slope of the best-fit line.
The data in Table 1.5.3 were obtained from a tensile test of a metal specimen with a rectangular cross section of 0.2011in.2 in area and a gage length (the length over which the elongation is measured) of 2.000 inches. The specimen was not loaded to failure. a. Generate a table of stress and strain values. b. Plot these values and draw a best-fit line to obtain a stress-strain curve. c.

How does a tensile stress differ from a compressive stress?
A tensile test was performed on a metal specimen with a diameter of 1 2 inch and a gage length (the length over which the elongation is measured) of 4 inches. The dam were plotted on a load-displacement graph. P vs. L. A best-fit line was drawn through the points, and the slope of the straight-line portion was calculated to be P/L =1392 kips/in. What is the modulus of elasticity?
Two line loads q1 and q2 of infinite lengths are acting on top of an elastic medium, as shown in Figure P8.6. Find the vertical stress increase at A.
EB and FG are two planes inside a soil element ABCD as shown in Figure 10.50. Stress conditions on the two planes are Plane EB: EB = 25 kN/m2; EB = +10 kN/m2 Plane FG: FG = 10 kN/m2; FG = 5 kN/m2 (Note: Mohrs circle sign conventions for stresses are used above) Given ; = 25, determine: a. The maximum and minimum principal stresses b. The angle between the planes EB and FG c. The external stresses on planes AB and BC that would cause the above internal stresses on planes EB and FG
