Roller supports are free to rotate and translate along the surface upon which the roller rests. The surface may be horizontal, vertical or slopped at any angle. Roller supports are commonly located at one end of long bridges in the form of bearing pads. This support allows bridge structure to expand and contract with temperature changes and without this expansion …

You can lock the vertical axis in relation to the front view during view rotation. This prevents the model from tipping and tilting about the horizon plane and creates the impression that the model is on a floor. Right-click in the graphics area and click Rotate about scene floor. The vertical axis locks in relationship to the front view.

Needle roller bearing is a special type of roller bearings that has cylindrical rollers that resemble needles because of their small diameter. Normally, the length of rollers in roller bearings is only slightly more than its diameter. When it comes to needle bearing, the length of rollers exceeds their diameter by at least four times.

Motion in a Vertical Circle. The motion of a mass on a string in a vertical circle includes a number of mechanical concepts. It must satisfy the constraints of centripetal force to remain in a circle, and must satisfy the demands of conservation of energy as gravitational potential energy is converted to kinetic energy when the mass moves downward. The velocity must increase as …

The vertical rotating shaft will need to be held in position so that it remains vertical with the gears meshed. Depending on the rotating weight, a pair of tapered roller bearings might do both jobs. They would probably be part of the gear box assembly. The motor torque needed to rotate the shaft and load is a separate issue.
