A six cylinder 3.2-liter engine operates on a four-stroke cycle at 2400 RPM. The compression ratio is 10.2:1. The bore and stroke are related as S=1.12*B. Calculate: 1. Clearance volume of one cylinder in cm3, L and in in3. 2. Bore and stroke in cm and in 3. Average piston speed in m/sec and ft/sec 4. Piston speed when the crank angle is θ=90° aTDC in m/sec

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false
