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.

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 cm? 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 cm and a diagram length of 0.85 cm. The pressure scale on the indicator diagram is set to 165 kN/m 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.
