Chapter 4, Problem 4.7QP
An aluminum alloy bar with a rectangular cross section that has a width of 12.5 mm, thickness of 6.25 mm, and a gauge length of 50 mm was tested in tension to fracture according to ASTM E-8 method. The load and deformation data were as shown in Table P4.7. Using a spreadsheet program, obtain the following:
a. A plot of the stress–strain relationship. Label the axes and show units.
b. A plot of the linear portion of the stress–strain relationship. Determine the modulus of elasticity using the best fit approach.
c. Proportional limit.
d. Yield stress at an offset strain of 0.002 m/m.
e. Tangent modulus at a stress of 450 MPa.
f. Secant modulus at a stress of 450 MPa.

A simply supported beam for a building interior with 18 ft span has a cross
section of 12 in width and 21 in overall depth. The beam is made with 5 ksi
compressive strength concrete and 60 ksi reinforcing steel. The beam supports a
uniform service superimposed dead load of 1.6 kip/ft, and a uniform service live
load of 80 psf throughout the span. The beams are laterally spaced 20 ft apart
c/c. Design this beam and show in a sketch.
The dam presented below is 180 m long (in the direction perpendicular to the plane of the
cross-section). For the water elevations given on the drawing:
a) Construct the flow net (minimum number of equipotential lines should be 10),
b) Calculate the rate of seepage for the entire dam,
c) Find the total uplift force on the dam (ignore barriers), and
d) Estimate the hydraulic gradient at points A, B, and D.
Recommended to use a spreadsheet to include all equations for calculations of potentials.
Using A36 steel select the lightest equal leg single angle member to resist a factored (LRFD) tensile load Pu = 167 kips. The member will be connected through one leg with one line of three 3/4-in Ø bolts spaced at 3 in between centers as shown. The edge distances Leh = Lev = 1.5 in. Use LRFD Method Use U from Table D3.1, Case 8. See attached (D3.1 Case 8, Shear Strength of Bolts, Table 1-7 Dimensions of Angles).

- Vehicles begin to arrive at an amusement park entrance at 8:00 A.M. at a rate of 1000veh/h. Some of these vehicles have electronic identifiers that allow them to enter the park immediately, beginning at 8:00 A.M., without stopping (they are billed remotely). All vehicles without such identifiers stop at a single processing booth, but they wait in line until it opens at 8:10 A.M. Once open, the operator processes vehicles at μ(t) = 8 + 0.5t [where μ(t) is in vehicles per minute and t is in minutes after 8:10 A.M.]. An observer notes that at 8:25 there are exactly 20 vehicles in the queue. What percent of arriving vehicles have electronic identifiers and what is the total delay (from the 8:00 A.M. until the queue clears) for those vehicles without the electronic identifiers (assume D/D/1 queuing)?arrow_forward1.
