Rolling Resistance: Problem Solving01:17

Rolling Resistance: Problem Solving

925
Rolling resistance, also known as rolling friction, is the force that resists the motion of a rolling object, such as a wheel, tire, or ball, when it moves over a surface. It is caused by the deformation of the object and the surface in contact with each other, as well as other factors like internal friction, hysteresis, and energy losses within the materials. Rolling resistance opposes the object's motion, requiring additional energy to overcome it and maintain movement. In practical...

Controller Configurations

439
Controller configurations are crucial in a car's cruise control system because they manage speed over time to maintain a consistent pace regardless of road conditions, thereby meeting design goals. In traditional control systems, fixed-configuration design involves predetermined controller placement. System performance modifications are known as compensation.
Control-system compensation involves various configurations, most commonly series or cascade compensation, in which the controller...

Rolling Resistance

754
When a solid cylinder rolls steadily on a rigid surface, the normal force applied by the surface on the cylinder is perpendicular to the tangent at the contact point. However, since no materials are entirely rigid, the surface's reaction to the cylinder involves a range of normal pressures.
For instance, imagine a hard cylinder rolling on a comparatively soft surface. The cylinder's weight compresses the surface beneath it. As the cylinder moves, the material in front of it slows down due to...

Area of Science:

  • Biomechanics
  • Rehabilitation Science
  • Musculoskeletal Health

Background:

  • Manual wheelchair users (MWUs) face high risks of upper extremity (UE) injury and pain.
  • UE pain significantly impairs mobility and independence for MWUs.
  • Motor variability in movement is increasingly linked to musculoskeletal pain.

Purpose of the Study:

  • To review investigations on the association between wheelchair propulsion variability and shoulder pain in MWUs.
  • To highlight the impact of shoulder pain on wheelchair propulsion patterns.
  • To propose future research directions incorporating motor variability metrics.

Main Methods:

  • Review of existing research examining wheelchair propulsion.
  • Analysis of motor variability in propulsion patterns.
  • Correlation of variability metrics with shoulder pain in MWUs.

Main Results:

  • Experimental data indicate that shoulder pain affects wheelchair propulsion variability in MWUs.
  • Variability in propulsion is a measurable consequence of shoulder pain.
  • This relationship suggests potential for novel insights through further research.

Conclusions:

  • Shoulder pain demonstrably alters wheelchair propulsion mechanics in MWUs.
  • Incorporating motor variability analysis in future studies is recommended.
  • Further research can leverage these findings to develop targeted interventions for UE pain in MWUs.
