The flywheel on a steam engine rotates 60 revolutions every 15 seconds what is the flywheel rate of revolution per second? need the unit rate too.

The flywheel rate of the flywheel is 4 revolutions per second.

Step-by-step explanation:

From Rotation Physics we understand that flywheel rotates at constant rate. In this case, angular speed (), measured in revolutions per second, is the number of revolutions done by the flywheel at a given interval of time. That is:

(Eq. 1)

Where:

- Number of revolutions done, measured in revolutions.

- Time, measured in seconds.

If we know that and , then the angular speed of the flywheel is:

The flywheel rate of the flywheel is 4 revolutions per second.

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

25.2

step-by-step explanation:

2+4x6-8/10= 25.2
