2007年8月30日 · If there is no friction and the hamster can keep running faster and faster forever then there is no limit until the hamster starts approaching the speed of light. (the relativistic hamster problem) The hamster does apply a torque to the wheel to move it but torque is just a force, you don't store up torque - you store angular momentum.

2009年12月6日 · The hamster's motion, specifically its running speed and direction, can greatly affect the rotational dynamics of the wheel. As the hamster runs, it exerts a force on the wheel, causing it to rotate. The direction and speed of the hamster's motion can determine the direction and speed of the wheel's rotation.

2004年10月26日 · After getting a drink of water, a hamster jumps onto an exercise wheel for a run. A few seconds later the hamster is running in place with a speed of 0.8 m/s. Find the work done by the hamster to get the exercise wheel moving, assuming it is a hoop of radius 0.10 m and mass 5.9 g. I'm not sure how to solve this one. I think you use

2008年11月4日 · A hamster runs in its wheel for 4.5 hours every night. If the wheel has a 6.8 cm radius and its average angular velocity is 3.0 radians per second, how far does the hamster run in one night? Homework Equations angular velocity = ang displacement / time The Attempt at a Solution 3 = angular displacement / 16200 seconds angular displacement = 48600

2004年6月24日 · Hamsters have been running in wheels of their own volition since the first kind person who thought to give them something to excercize with put one at its disposal. One does not have to prod a hamster to run! They love doing it, and spend hours at it every night in sheer ecstasy! The cruelty would be in trying to stop them from running.

2013年3月17日 · Being rotated inside a giant hamster wheel would cause the G Forces experienced by a human to increase significantly, due to the constant acceleration and change in direction. This would be similar to the experience of riding a roller coaster, where the G Forces can reach up to 4 or 5 Gs.

2009年9月27日 · In summary, the hamster runs for 3.1 hours at an average angular velocity of 3.0 radians per second on a wheel with a 6.8 cm radius. To determine how far the hamster runs in one night, we need to convert the angular velocity to turns per second and find the time it takes to complete one full revolution.

2024年2月3日 · Then I searched high speed paddlewheel boat, and found US Patent 6743064, titled High-speed Paddle Wheel Catamaran. This patent puts the paddlewheel in a tunnel as alluded to in Post #5 by @Baluncore. And many more good hits.

2009年9月5日 · The energy of one wheel rotating at a velocity of w (in radians per sec) is E = (1/2) I w 2 = (3/8) m (Rw) 2 But Rw is just the velocity of the rolling wheel with radius R, so Rw= v (meters per sec). So for one tire, the energy is E = (3/8) m v 2 For a wheel (rim plus tire) mass of 35.5 pounds (16.1 Kg) and 60 mph (26.8 meters per sec)

2024年5月13日 · The manual says "The left hand motor has a bad connection. Check the connections to the left hand motor." But the motor connection was checked, also the whole motor has been replaced on the first wheelchair, but the problem persisted.
