Calculate the moment of inertia of a suitable flywheel.
Calculate the mass required if the radius of gyration is to be 0.3 m.
Q3/ A vertical double acting steam engine develops 80 kW at 240 rpm. The maximum fluctuation of energy is 25% of the work done per stroke. The maximum and minimum speeds are not to vary more than +1% of the mean speed. Find the mass of the flywheel, if the radius of gyration is 0.65 m.
A spur gear is mounted on a 28mm shaft at equal distances from two supporting bearing.The gear
pitch circle is 7in and its pressure angle o = 15°. Its gearbox transmit 15kW.The shaft and gear
turns together with an angular velocity of 30 rad/s. Select the most suitable bearing and calculate
