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)

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
