Question

A press tool machine uses a flywheel in the form of a solid steel disc 0.7 m diameter and 0.1 m thick rotating with a mean speed of 60 rev/min. The density of the steel is 7830 kg/m^3. The press is operated once every 5 revolutions and a torque of 2000 Nm is exerted on the tool for a duration of 0.05 seconds. The energy absorbed is replaced during the rest of the cycle. Sketch the torque angle diagram and determine the following. The mass of the flywheel .The moment of inertia .The work done during the pressing operation .The coefficient of fluctuation of speed.

2. A press tool machine uses a flywheel in the form of a solid steel disc 0.7 m diameter and 0.1 m thick
rotating with a mean speed of 60 rev/min. The density of the steel is 7830 kg/m*. The press is
operated once every 5 revolutions and a torque of 2000 Nm is exerted on the tool for a duration of
0.05 seconds. The energy absorbed is replaced during the rest of the cycle.
Sketch the torque angle diagram and determine the following.
The mass of the flywheel (301.33 kg)
The moment of inertia (18.46 kg m')
The work done during the pressing operation (628.3J)
The coefficient of fluctuation of speed (0.8623)
The maximum and minimum speeds of the flywheel
(85.9 and 34.1 rev/min).
