During the compression stroke of a certain gasoline engine, the pressure increases from 1.00 atm to 19.0 atm. The process is adiabatic and the air-fuel mixture behaves as a diatomic ideal gas. (a) By what factor does the volume change? Vfinal = Vinitial (b) By what factor does the temperature change? Trinal = Tinitial Assume the compression starts with 0.016 mole of gas at 28.5°C. (c) Find the value of Q that characterizes the process. (d) Find the value of AEnt that characterizes the process. (e) Find the value of W that characterizes the process.

Using the Pappus-Guldinus Theorem #2, how many grams of gold are needed for this ring? The density of gold is 19.3 g/cm³. 2 cm 1 cm 0.5 cm 0.5 cm

Question 6 a) The bore of each cylinder in a six-cylinder car engine is 45 mm and the stroke for each piston is 125 mm. calculate the cubic capacity of the engine in cubic centimetres (cm³); and calculate the clearance volume per cylinder for a compression ratio, r, of 8.75. b) The bore of each cylinder in a four-cylinder four-stroke internal combustion engine is 38 mm and the stroke of each piston is 165 mm. During testing, the engine runs at 180 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 3.4 cm² and a diagram length of 1.2 cm. The pressure scale on the indictor diagram is set to 150 kN/m² per cm. Calculate the mean effective pressure (m.e.p) and the indicated power developed by this four-cylinder four-stroke engine. c) Figure Q6c shows a pulley system with a suspended load w of 2000 N. Calculate the following: (i) (ii) (iii) (iv) The effort force (FEffort) necessary to lift and hold a load of 2000 N. The ideal mechanical advantage…
