In the context of our teaching, which one of the
below statements is mostly correct about in
detailed design of a component?
In the reporting, I do not need to include the
reasoning for my design decision for a good
quality report.
I cannot use appendix, so I am struck with the
word limit for reporting.
For a good clarity, I should not explicitly
report what are the key dimensions and their
tolerances in the drawing and in the body of
text.
The word count limit for detailed design
report is 160O.
Some international (e.g., ISO) standards become national standards. Give one example, citing the original standard and its national counterpart.
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.
