CEE 216 Civil Engineering Materials Steel 1. A 32-mm rebar with a gauge length of 200 mm was subjected to tension to fracture according to ASTM E-8 method. The load and deformation data collected are shown in Table 1. Create a spreadsheet to complete the following. Table 1. Load and displacement data for a 32-mm rebar sample subjected to an increasing tensile load a. Create a plot of stress-strain. Label the axes and show...
4.A thin-walled cylindrical column carries a weightless arch and is loaded as shown in Figure 4. The column has an internal diameter of 250 mm with a thickness of 2 mm Given: E-200 GPa and 0.3 The answer to each part of the question is to be used for subsequent parts (a)Determine the stresses on the outer surface of the cylinder at points A and B due to (8 marks) (b) Determine the minimum internal pressure p required if the...
3. Power transmission is an important engineering application and relies on the integrity of the shaft designs. Assume a solid, circular steel shaft with a uniform diameter d 50 mm and a total length I3 m. At its midpoint, a belt passes over a pulley and delivers 50 kW power to the shaft. This power is used to drive two machines at either end of the shaft. Machine 1 consumes P1 20 kW and machine 2 uses P230 KW. The...

Problem 3 The length of the 2 mm diameter steel wire CD has been adjusted so that with no load applied, a gap of 1.5 mm exists between the end B of the rigid beam ACB and a contact point E. Knowing that E= 200 GPa, determine the distance x where a 20 kg block should be placed on the beam in order to cause contact between B and E. 250 mm 20 kg B 1.5 mm 80 mm

Problem 2 10 pts A cylindrical pressure vessel with wall thickness t-5 mm and inside radius r 150 mm is design to hold high pressure. The vessel design requires a safety factor against yielding Xo -2, and leak-before-break with a safety factor X-5 on the critical crack length; that is, the critical crack length ce must be at least Xt. Calculate the maximum pressure, p, if the vessel is...
