Chapter 4 Shear and Moment In Beams

The intensity w of this loading is expressed as force per unit length (lb/ft, N/m, etc.) The load distribution may be uniform, as shown in Fig.4.1(b), or it may vary with distance along the beam, as in Fig.4.1(c). The weight of the beam is an example of distributed loading, but its magnitude is usually small compared to the loads applied to

Roller Clutch Bearing Troubleshooting Fishing Reels

Reel Bearings 301: Maintenance, Design, and Troubleshooting (continued). Roller Clutch Bearing Troubleshooting: Roller clutch bearings are used in many reels to prevent reverse rotation of the handle shaft and other drive components. Some reels may also use ratchets or cogs in addition to this bearing, to ensure the spool does not rotate backward and to reduce handle back-play.

Support and Connection Types - MIT

ROLLER SUPPORTS Roller supports are free to rotate and translate along the surface upon which the roller rests. The surface can be horizontal, vertical, or sloped at any angle. The resulting reaction force is always a single force that is perpendicular to, and away from, the surface. Roller supports are commonly located at one end of long bridges.

The shaft rotation could not be used for the triggering due to different velocity of the shaft and the cage. The theoretical ratio of these velocities is 0.41, however due to a slight variance of the roller motion, the practical ratio is not perfectly constant which will lead to a desynchronization of the measurements.
