Part of the gear train for a Lath machine tool is shown. Compound gears 2 and 3 slide on a splined shaft so that gear 3 can mesh with gear 4 or gear 2 can mesh with gear 6. Also, compound gears 14 and 15 slide on a splined shaft so that gear 14 can mesh with gear 16 or gear 15 can mesh with gear 17. the angular velocity ratio for the transmission is given by:

Where ωo = ω16 = ω17 and ωi = ω2 = ω3

a/ What should be the two possibility of y. (2 Marks).
b/ What should be the two possibility of x. (2 Marks).
c/ If gear 3 meshes with gear 4, calculate the two possible spindle speeds for a motor speed of 1800 rpm?
(3 Marks).
d/ Now assume that gear 14 meshes with gear 16, and gear 2 meshes with gear 6.
Calculate the number of tooth N6 of gear 6 if N2=10 tooth and ωo=130 rpm? (3 Marks).

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.
