Going too slow on the band will • make better cuts
• cause the stock to burn
• reduce accuracy
• none of the above

The stock being cut (band saw) cannot be
• held flat
• strait
• wood
• turned sharply

For sharp cuts, you must make several cuts from the outside edge
• fast
• open
• sharp
• relief

The band saw guard should be above the wok piece.
• 1 inch
• 2 inches
• 1/2 inches
• 1/4 inches

Where should your fingers be when cutting on the band saw?
• anywhere as long as the stock is well supported
• pointing away from the blade
• must use mitre gauge and should not have hands on the table
• push stock with hands towards the blade of band saw

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.

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.
