Parts arrive at a machine shop with EXPO (25) interarrival times (all times are in minutes); the first part arrives at time zero. The shop has two machines, and arriving parts are assigned to one of the machines (50% probability). Except for the processing times, both machines operate in the same fashion. When a part enters a machine area, it requires operator attention to set up the part on the machine (there is only one operator in the shop). After the part is set up. The machine can process it without the operator. Upon completion of the processing, the operator is once again required to remove the part. After completion, the parts exit the system (parts have to go to only one machine). The same operator does all setups and part removals, with priority given the machine waiting the longest for an operator. The times are as below: Machine number Setup Time Process Time Removal Time
1 TRIA (8, 11, 16) TRIA (20, 23, 26) TRIA (7, 9, 12)
2 TRIA (5, 8, 14) TRIA (11, 15, 20) TRIA (4, 6, 8)

Required:
Run the simulation for 25,000 minutes, and observe statistics on machine utilization, operator utilization.

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
