A 3"-diameter, 5"-long gas-piston assembly contains air at STP. (STP: Standard Temperature and Pressure conditions, 300K and 1 atm. At these conditions the air density is approximately 1.2kg/m3.) Calculate the necessary piston displacement in order to increase the pressure to 45 atm (typical of a diesel engine) varying linearly with displacement (i.e. the pressure varies linearly with displacement) during an adiabatic compression that will increase the gas’ internal energy by 1.2kJ.

Why is it a good idea to create value stream process maps?

Why is edge bead more common in thick SU-8 compared to thin Shipley 1827? How can we minimize the edge bead problem (describe all possible methods)? What kind of issues does edge bead produce in soft bake and exposure?

A steel wire with a cross-section area 2.5X10^-3 m2 and a length of 10 m is used to pull a truck on the road. The truck is 10 tons and the friction coefficient between the tires and road is 0.25N/kg. Steel has a Young’s modulus 250MPa.

Suppose this wire contain surface cracks. Determine the largest linear size of the surface crack so that the wire will not fail due to fracture in this application. Kc = 0.1 MPa m^0.5

(1) Problem 9-33 (show the solution process in detail)

9-33 An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process, air is at 95 kPa and 27°C, and 750 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Taking into account the variation of specific heats with temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. Answers: (a) 3898 kPa, 1539 K, (b) 392.4 kJ/kg, (c) 52.3 percent, (d) 495 kPa

(2) Problem 9-33 but assume constant specific heats.

Two trains of equal weight, moving with velocities of 30 miles an hour each and in opposite directions collide. Show that the loss of energy caused by the impact is the same as in the case of a train moving at 60 miles an hour striking another at rest. In the latter case, find the velocity with which the debris will be moved along the track. Also show that before impact the total energy in the one case is doubled that in the other
