Question

The flywheel of a steam engine runs with a constant angular velocity of 200 rev/min. When steam is shut off, the friction of the bearings and of the air stops the wheel in 2.3 h.

**(a)** What is the constant angular acceleration, in revolutions per minute-squared, of the wheel during the slowdown?

**(b)** How many revolutions does the wheel make before stopping? **(c)** At the instant the flywheel is turning at 100 rev/min, what is the tangential component of the linear acceleration of a flywheel particle that is 36 cm from the axis of rotation?

**(d)** What is the magnitude of the net linear acceleration of the particle in (c)?

Step 1

Solution:

Since we are entitled to answer up to 3 sub-parts, we’ll answer the first 3 as you have not mentioned the subparts you need help with. Please resubmit the question and specify the other subparts you’d like to get answered

Step 2

Given:

The angular velocity of the flywheel 200 rev/min.

The wheel stops of after 2.3 h.
