Students making sense of motion in a vertical roller
2019-9-25 Circular motion is one of the central topics in high-school physics curriculum, but most physics students enter university with only a partial understanding of the forces involved (see e.g. [1, 2]).Carousels, swings and roller coasters offer the possibility to experience these forces in our own body, including the varying forces during circular motion in a vertical plane.

SIMPLIFICATION OF FORCE AND COUPLE SYSTEMS
2015-10-14 SIMPLIFICATION OF FORCE AND COUPLE SYSTEM (Section 4.7) When a number of forces and couple moments are acting on a body, it is easier to understand their overall effect on the body if they are combined into a single force and couple moment having the same external effect. The two force and couple systems are called equivalent systems since they

Klatt Roller conveyors
Roller conveyors are used for a cost-efficient simplification of the internal flow of goods. They are used for horizontal transportation of the units to be moved. Depending on loading devices, goods, weight and other specifications, roller tracks are designed by using different types of rollers which can be moved via chains or toothed belts.

2022-1-1 For further simplification of rolling model, the flat roller with a friction coefficient of 0.5 or higher value can be used to represent the profiled roller. The initial condition accounting for the WAAM-induced PS and RS plays significant roles in the predictions of final PS and RS by the rolling model for relatively low rolling load.
