The flywheel of a steam engine runs

Reference no: EM13654245

The flywheel of a steam engine runs with a constant angular speed of 150 rev/min. When steam is shut off, the friction of the bearings stops the wheel in 2.7 h. (a) What is the constant angular acceleration, in revolutions per minute-squared, of the wheel during the slowdown? 1 rev/min2 (b) How many rotations does the wheel make before stopping? 2 rotations (c) At the instant the flywheel is turning at 75 rev/min, what is the tangential component of the linear acceleration of a flywheel particle that is 50 cm from the axis of rotation? 3 mm/s2 (d) What is the magnitude of the net linear acceleration of the particle in (c)? 4 m/s2
