Question: quotprimary and secondary forces and couple acting on which of...

Question details
"Primary and secondary forces and couple acting on which of the component? 1. Reciprocating mass 2. Crankshaft 3. Cylinder

In a four cylinder in-line IC engine, the mass of reciprocating parts of cylinder number 1 and 4 are 100 kg and that of cylinder number 2 and 3 are 173 kg. If the crank radius is 150 mm, length of connecting rod is 450 mm and engine speed is 1200 rpm, determine the primary and secondary forces and couples. The cylinders are placed 600 mm apart as shown in Figure Q2 2 3 3 0.6 mm 0.6 m 60° 30° 30° 60 0.6tm 2 Primary crank Figure Q2 (CO2-8 marks)
