An engineer machines annealed copper in an orthogonal machining experiment. given: cutting speed: 4m/min(13.1 ft/min) depth of cut: 1.17 mm (0.046 in) machine efficiency; 98% width of cut 6 mm (0.236 in) tool material: aluminum oxide coated carbide tool geometry: 2degree relief angle. -5degree rake angle, 5degree clearance angle. 1.75mm (0.069 in) nose radius cutting fluid: synthetic oil (coefficient of friction -0.1) use us standard units for all your work. calculate the shear angle when machining with synthetic oil. calculate the required horse power for the machine engine (motor).

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct
