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 meas- ured) of 4 inches. The data were plotted on a load-displacement graph, P vs. AL. A best-fit line was drawn through the points, and the slope of the straight-line portion was calculated to be P/AL = 1392 kips/in. What is the modulus of elasticity? BI

Question 2 In designing prosthetic sockets, the latter will need to be experimentally tested for their structural integrity. Figure 2 shows one such design of a prosthetic socket which is made of carbon fibre composite. Strain gauges are installed to record the strains at various locations of the legs during walking and the readings are recorded using a telemetry system to detemine the critical stressed area. At a particular strain gauge location indicated in Figure 2, the readings recorded by one of the 45° strain gauge rosettes are: Ea = 2500 x 10*, es = 1500 x 10°, & = -950 x 10* Using Mohr's Cicle or otherwise, detemine: (a) the principal strains and the direction of the maximum principal strain relative to the gauge "a". (b) the corresponding principal stresses and sketch the results on a properly oriented element. You may assume that the prosthetic socket is made of polypropylene whose Young's modulus of 1.0 GPa and Poisson ratio of 0.3. Figure 2

i. If you know that any strain gauge has a sensitivity towards temperature.In other words, any change in the temperature could also affect theresistance value. How can we get a correct reading from strain gaugesand get rid of the temperature effect?ii. In an AC LVDT system, measuring the output voltage alone gives anindication of the displacement from the center, but not the direction ofdisplacement. Explain why, and also explain a method for solving thisproblem.iii. In a vortex flow meter, there are many methods that could be used tomeasure the effect of vortices and measure the flow rate. Explain howvortices could occur in this flow meter, and explain three methods thatcould be used for measuring the effects of vortices in a vortex flowmeter.iv.
