7. (15) An accelerometer has a mass of 1.5 g and silicon sensor parts. The four flexural members are 110 microns long and their cross section is a square, with 4 microns by 4 microns. Silicon has a modulus of elasticity of 150 GPa. (a) Find the relation between the acceleration and the strain measured by any of the piezoresistive sensors on the vertical flexural members. (b) Calculate the strain at an acceleration of 2.1g if the strain gauges are small and placed 0.03 mm from the center of the flexural member. (State your assumptions. If you are missing any information to solve the problem, leave those as variables, if applicable)

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Give heat transfer applications for the following, (i) gas turbines (propulsion) ) gas turbines (power generation). (iii) steam turbines. (iv) combined heat and power (chp). (v) automotive engines

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
