  • With one rotation, the wheel advances one entire circumference.
  • The circumference is radius times (2 x pi).
  • To convert from centimeters to meters, divide by 100.
  • Finally, just divide the total number of meters by the circumference (in meters), to get the number of turns.

What is the mechanical advantage of a a wheel and axel?

The mechanical advantage of a wheel and axle is the ratio of the radius of the wheel to the radius of the axle. Ex:- Suppose the radius of the wheel is four times greater than the radius of the axle, every time you turn the wheel once, your force will be multiplied four times.


How many times will the wheel of a car rotate in a journey of 88km if the diameter of the wheel is 56cm?

50,020 times


What is the radius in inches of the wheel A wheel made 3000 revolutions while traveling 45000 pi inches in a stright line along the ground . give answer and explanation?

If the wheel made 3000 revolutions and covered 45000 pi inches, then one revolution would cover 15 pi inches. That is the circumference. The circumference is equal to 2 times the radius times pi. Then the radius is 7.5 inches.


What part does a wheel and tire rotate on?

They rotate on the wheel hub, which houses the wheel bearing.


How do you convert rpm to meter per second?

You have to know how far the measurement point is from the center of the rotation.The farther out it is, the more meters per second it will cover.(At the same RPM, a 10-ft tractor tire covers more meters per second than a skate-board wheel does.)When you know the 'radius' of the wheel in meters,the speed of a point on the rim is(Radius) times (pi/30) times (RPM) = (Radius) times (0.1047) times (RPM) meters per second. (rounded)

What is the IMA of a wheel and axle?

The IMA of a wheel and axle is the radius of wheel divided by the radius of the axle.
