36 36 Example During a trial on steam engine, it is found that the acceleration of piston is 36 m/s 2 when the crank has moved 30 from IDC. The net effective steam pressure on piston is 0.5 N/mm 2 and frictional resistance is equivalent to a force of 600 N. The diameter of piston is 300 mm & mass of reciprocating parts is 180 kg. If the length of crank is 300 mm & ratio of ConRod length to crank length is 4.5, find: 1. Reaction on guide bars 2. Thrust on crank shaft bearings 3. Turning moment on crank shaft
37 37 Example A vertical petrol engine 100 mm diameter & 120 mm stroke has a ConRod 250 mm long. The mass of piston is 1.1 kg. The speed is 2000 rpm.

Determine the dynamical equivalent twomass system of the ConRod if one of the masses is located at the small end center.
50 50 Example A ConRod is suspended from a point 25 mm above the center of small end, and 650 mm above its center of gravity, its mass being 37.5 kg. When permitted to oscillate, time period is found to be 1.87 seconds. Find dynamical equivalent system constituted of two masses, one of which is located at the small end center.

The CG falls at a point 100 mm from the gudgeon pin along the line of centers. The radius of gyration about an axis through the CG perpendicular to the plane of rotation is 110 mm. 59
