Well, well, well, looks like someone's got a math problem! If the wheel of a bicycle makes 1000 revolutions in traveling 628m, we can use the formula Circumference = 2 * π * radius to find the radius. First, we find the circumference by dividing the distance traveled by the number of revolutions. Then, we plug that value into the formula and solve for the radius. Voila, you've got your answer!
1 revolution = 2PI radian. 2 revolutions = 4PI radian The angular speed of the Ferris wheel is 4PI radians . Multiply by the radius. The linear speed is 100PI feet per minute.
The relationship between revolutions per minute (RPM) and relative centrifugal force (xg) is: g = (1.118 × 10-5) R S2 where g is the relative centrifugal force, R is the radius of the rotor in centimeters, and S is the speed of the centrifuge in revolutions per minute. You can use this for any centrifuge, just measure the radius of the rotor from the center to outer edge.
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.
After any whole number of revolutions, the total displacement is zeroand so the average velocity is zero.At any instant, the magnitude (speed component) of instantaneous velocity is(pi) x (distance from center of rotation) x (RPM / 30) units per second.
One formula is: centripetal force = speed2 / radius. Solve it for speed, then convert that to revolutions per second.One formula is: centripetal force = speed2 / radius. Solve it for speed, then convert that to revolutions per second.One formula is: centripetal force = speed2 / radius. Solve it for speed, then convert that to revolutions per second.One formula is: centripetal force = speed2 / radius. Solve it for speed, then convert that to revolutions per second.
Assuming rmp means revolutions per minutes, 2*r*pi*rpm (inches/minute).
Distance is number of revolutions times circumference. So divide the distance by the revolutions to get the circumference. Then divide the circumference by pi to get the diameter, and divide that by 2 to get the radius.
In each revolution, the wheel would advance 2 x pi x radius. Multiply this by the number of revolutions.
As the radius of rotation decreases, the number of revolutions of a rubber stopper increases. This is due to the conservation of angular momentum - with a smaller radius, the rotational speed must increase to maintain the same angular momentum.
