Identify any major external and internal forces that you can expect to be present on the mechanism inside the jigsaw power tool (gears and scotch yoke component). Does turning the blade or twisting by the user change the forces? How has the design been supported against these forces?

Pretend you are a prospector and a blacksmith who wants to make a belt buckle made of iron. (Your pants keep slipping downward and you have a leather belt, but no buckle.) What mineral are you looking for, and where? What are you going to do to turn your mineral into a belt buckle. (You are going to make it by yourself.) Describe every step along the way, in detail.

An air-standard dual cycle has a compression ratio of 9.1 and displacement of Vd = 2.2 L. At the beginning of compression, p1 = 95 kPa, and T1 = 290 K. The heat addition is 4.75 kJ, with one quarter added at constant volume and the rest added at constant pressure. Determine: a) each of the unknown temperatures at the various states, in K. b) the net work of the cycle, in kJ. c) the power developed at 3000 cycles per minute, in kW. d) the thermal efficiency. e) the mean effective pressure, in kPa.

(a)Air, which can be assumed to behave as an ideal gas, undergoes a process from 150kPa and 400K to 600kPa and 500K within a piston cylinder. Can this process occur adiabatically? (Think about what the limitations on ???? are to answer this question). (b)Now consider air which is compressed in an air compressor adiabatically from 150kPa and 400K to 1000K and 600kPa. It enters the air compressor with a mass flow rate of 1kg/s. Determine the rate of entropy produced during the process in ??j/(s*k)
