L50 DKI & DK2: 9.00 pm 10.30 pm QUESTION 2 (15 marks) (a) A twin cylinder V-engine has cylinders set at 120°, with both piston connected to a single crank as shown in Figure Q2(a). The stroke is 140 mm and the connecting rods are 210 mm long. The reciprocating mass per cylinder is 1.2 kg. Determine the maximum primary and secondary forces acting on the frame of the engine when running at 2,400 rpm. (b) Figure Q2(b) shows 4...

4. An engine connecting rod is 25 cm between the centre-lines of the big and small ends. The big end bearing is 5 cm diameter and the small end is 2.5 cm diameter. When the connecting rod is suspended on a horizontal knife edge about its big end and vibrated as a compound pendulum, the measured frequency of vibration is 1.145 Hz. When the experiment is repeated with the rod suspended from the small end, the measured frequency of vibration...

In the engine system shown -250 mm and b 100 mm. The connecting rod BD is assumed to be a 1.2-kg uniform slender rod and is attached to the 1.8-kg piston P. The AB rod is rotating counterclockwise at a constant angular velocity of 15 rads/s. Determine all the reactionary forces as a function of θ and plot these forces as a function of θ. At what angle(s) is the reaction force...
