Draw a fourbar linkage with L1 = 10 cm, L2 = 3 cm L3 = 6 cm and L4 = 6 cm, with LaTeX: \theta_2θ 2= 45o. Consider both configurations in your drawing, namely the open and closed. Measure your transmission angles and indicate which is which. Do you see a difference in values? (0.25 point - lengths measurements)
(0.5 point - angles measurements)
(0.5 point - both configurations)
(0.5 point - neatness)
(0.5 points – links dwg)
(0.25 points - transmission angles measurements)

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.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
