Question 4 a) Each cylinder in a four-cylinder car engine has a bore diameter of 63.53 mm and the stroke for each piston is 175.00 mm. Calculate the cubic capacity of the engine in cm3 and calculate the clearance volume per cylinder for a compression ratio, r, of 6.25. b) The bore diameter of each cylinder in a six-cylinder four-stroke internal combustion engine is 32 mm and the stroke of each piston is 125 mm. During testing, the engine runs at 1450 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 2.90 cm² and a diagram length of 0.85 cm. The pressure scale on the indicator diagram is set to 165 kN/m² per cm. Calculate the mean effective pressure (m.e.p) and the indicated power in kilowatts (kW) developed by this six-cylinder four-stroke engine. Give your answer to 2 decimal places. c) A hollow connecting rod has an inner diameter of 26.25 mm and is subjected to an axial tensile load of 500 MN. If the maximum allowable stress for this…

A mechanical press is powered by a 23-kW motor and operates at 40 strokes per minute. It uses a flywheel, so that the crankshaft speed does not vary appreciably during the stroke. If the stroke is 150 mm, what is the maxumum const.ant force rhat can be exerted over the entire stroke length?
Explain why these two formulas are correct. Explain the positive and negative signs and why they are for the stress_i and stress_ii. It would help if there is a drawing. thank you!
Refer to drawing 21A033, what is dimension G? (Please note that you can't just assume the hub protrudes equally on both sides as it may not) All abbreviations are standard
