Four strain gauges are mounted on a cantilever beam in a configuration like that shown in Error! Reference source not found. 6. It is used to measure vibrational bending moment that is applied to the beam itself. The specifications of the load cell are given as follows .Modulus of Elasticity: E-120 GPa · Beam dimensions (Length × Height (h) × Width (b)): 25cm × 0.75cm × 2.5cm .Non-deflected resistances of the strain gauges-3002 Strain gauge factor-3 .Wheatstone bridge voltage supply 6 Volts. The bending moment is to be interpreted on a computer via a 12 bit A/D converter with measurement range 0 to 5 Volts. The required resolution is 0.01 Nm(bit step). Moreover, the bending moment is required to be band pass filtered with a transfer function that has a quality factor of 1.2 and a cut off frequency of 1000 rad/s. Please design an analogue schematic that can be used to achieve all of the aforementioned objectives. In your solution, please 1. Include the solution (with answer) to how the sensitivity of the Wheatstone bridge output () is calculated 2. Include the solution that determines the required total gain of the analogue circuit 3. Calculate the range of moment (in Nm) that can be measured by the proposed design. 4. A complete schematic of your circuit. If there are multiple major sections in your schematic then the purpose of each one shall be clearly shown either by well-known names or by a clear short description 5. All passive component values in your circuit shall be designed with appropriate numbers and any associated transfer functions or static gain formulae shall be either derived or referenced
