On what produced part below, show a simple sketch on how the flatness on the part may be verified and how the resultant flatness tolerance zone is defined. Please refer to attached image.
Select the correct statements regarding the addition of moments. (Select 3) Moments have directions, so a negative value implies it is along the opposite direction from the reference direction. All the moments need to have the same reference point/pivot in order to add together. Calculate each moment by multiplying each force with its distance to the reference point, and add all values together, regardless of their direction. You have to define the reference direction first, either clockwise or counter-clockwise.

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.

In the context of our teaching and learning, which one of the below statements is mostly correct about in drawing and communication of detailed design of a component? I do not know SolidWorks well enough, so I will ask my fried to do it for me. Using a pencil and rule to show the key dimensions for the key functions and their tolerances is adequate for this course work. I do not know the SolidWorks well enough, so I must learn and use AutoCAD for drawing. I must use SolidWorks to draw the competent and for its dimensioning.
