XYZ is a company who sells mini milling machines to universities for educational purposes. The company observes the number of machines on its hand (call it i) at the beginning of a month. If at the beginning of a month i ≤ 1, then the company orders 3 - i machines (so, the number of inventories is completed to 3). If i ≥ 2, then 0 machines are ordered. It is known that delivery of all ordered machines is immediate. The customers are equally likely to demand 0, 1, 2, or 3 machines from XYZ during the month. After fulfilling these demands, the company observes the inventory level at the beginning of the next month. a. Define the states b. Construct the one-step transition matrix.

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.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

Condition monitoring is a major component of. (clo4) a)- predictive maintenance. b)-preventive maintenance c)-proactive maintenance d)-reactive maintenance.
