Question

A certain machine requires a torque of (1500 + 200sind)Nm to drive it,
where 0 is the angle of rotation of the shaft. The machine is directly coupled
to an engine which produces a torque of (1500 + 200sino)Nm. The flywheel
and other rotating parts attached to the engine have a mass of 300kg at a
radius of gyration of 200mm. If the mean speed is 200rpm, find:
The fluctuation of energy
a.
b. The total percentage fluctuation of speed
The maximum and the minimum angular acceleration of the flywheel
and the corresponding shaft positions.​

Answer 1

Answer:

The machine is directly coupled ... and other rotating parts attached to the engine have a mass of ... radius of gyration of 200mm. ... and the corresponding shaft positions.
