An engineer is tasked to choose the most appropriate type of strain measurement technique for following applications. Help her with matching each strain gauge with its application. Semiconductor strain gauge 1. health monitoring of a bridge Metallic strain gauge 2. tensile test of metals photo-elasticity 4. Fiber-optic Bragg grating 3. analyzing strain in denture materials manufacturing a load cell (force transducer) sensors

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. Explain in details how can we use a capacitor to indicate the lever ofwater in a tank (use drawings and electrical diagram to elaborate on yourexplanation).Page 5 of 63v. Bimetallic strip could be used as a temperature detector. Explain…

If a constant stress is applied and the strain is monitored with time for a viscoelastic material, which of the following is TRUE Select one: O a. Strain will always increase linearly as long as the stress is applied. b. Strain will increase as long as the stress is applied but rate of strain will change with time. c. If the stress is removed, the strain will instantaneously become zero. d. Strain will develop instantaneously and remain constant thereafter. e. None of these options

Strain gauges are a standard sensor to convert deformation  into an electrical signal and are used in many applications.  Describe how train gauges could be used to measure (i) acceleration; (ii) fluid pressure.  Use a sketch for each case to illustrate how they are used.
