Step sizes of the pulley are 1.5”, 2”, 2.5” and 4”. It is easily connected to a support stand with a right-angle clamp. …

A Gyroscope is a fascinating mechanical device that at time seems to defy the laws of gravity. The unique characteristic of a gyroscope is that once it is set spinning, it tends to want to remain in its original plane regardless of rotation of its housing. The tendency to resist change in direction…
