Q-1 (25 pts An engine with five cylinders in-line have successive cranks apart. The effective reciprocating mass for each cylinder is 2 kg- the connecting rod is 420 mm long. balance at 144"C and pitched at 350 mm ig.Eamine the balance of primary and secondary forces and state as balanced or unbalanced, and if unbalanced state the magnitude of unbalanced magnitude. Assume the end b earings are symmetrically located at 1600 mm apart. The firing order is : 1, 5,...
Q-1 (25 pts) An engine with five cylinders in-line have success apart. The effective reciprocating mass for each cylin ive cranks at 144"C and pitched at 350 mm der is 2 kg, the crank radius is 105 mm and mm long. Examine the balance of primary and secondary forces and ed to state as balanced or unbalanced, and if unbalanced state the the connecting rod is 420 couples. (you are expect magnitude of unbalanced magnitude. Assume the end bearings are...
Q-1 (25 pts) An engine with three cylinders in-line have successive cranks at 240°C and pitched at 350 mm apart. The effective reciprocating and the connecting rod is 450 mm long. If the engine runs at 955 rpm, ,mass for each cylinder is 12 kg, the crank radius is 100 mm a. Show that primary and secondary forces are balanced b. Determine the reactions at the end bearings A and B due to primary couple effects. c. State the angular...
2. An engine has four cylinders arranged in two Vee banks, all being mounted symmetrically, above the main shaft. Each bank consists of two cylinders whose centre-lines are inclined at 90 to one another and whose connecting rods act on a single crankpin. The cranks of the two banks are set 180° apart a) Investigate the state of balance of the engine with respect to primary and secondary forces and couples and detemine the magnitude of any unbalanced forces or...
