Frictional Forces on Flat Belts01:28

Frictional Forces on Flat Belts

885
Flat belts are commonly used in various industrial applications for transmitting power from one pulley to another. When a flat belt is wrapped around a set of pulleys, it experiences different tensions at the driving pulley ends due to the friction between the belt and pulley surface. When the pulley moves in a counterclockwise direction, the tension T2 on the opposite side of the pulley where the belt is moving away from is higher than the tension T1 on the side where the belt is moving...

Rolling Resistance: Problem Solving01:17

Rolling Resistance: Problem Solving

305
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...

Two-Dimensional Force System: Problem Solving

552
Solving problems related to two-dimensional force systems is an essential aspect of mechanics and engineering. By applying the principles of vector analysis and force equilibrium, one can determine the effect of multiple forces acting on an object in a two-dimensional space.
The first step to solving a two-dimensional force system problem is to draw a free-body diagram of the object under consideration. This diagram helps identify all the external forces acting on the object, including their...

Three-Dimensional Force System:Problem Solving

657
A three-dimensional force system refers to a scenario in which three forces act simultaneously in three different directions. This type of problem is commonly encountered in physics and engineering, where it is necessary to calculate the resultant force on the system, which can then be used to predict or analyze the behavior of the object or structure under consideration.
To solve a three-dimensional force system, first resolve each force into its respective scalar components. Do this using...

Controller Configurations01:22

Controller Configurations

89
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...

Hierarchy of Motor Control01:18

Hierarchy of Motor Control

2.5K
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.

Area of Science:

  • Human-computer interaction
  • Biomechanics
  • Architectural psychology

Background:

  • Inclusive design extends beyond physical accessibility to sensory considerations.
  • Repetitive visual patterns in architecture can induce sensory burdens like dizziness and visual discomfort.

Purpose of the Study:

  • To assess the influence of different repetitive visual patterns on human gait and stability.
  • To evaluate the sensory discomfort caused by these patterns in a virtual reality environment.

Main Methods:

  • Eight participants walked in a virtual reality environment displaying random dots, stripes, and wave patterns (colored and greyscale).
  • Motion capture and electromyography (EMG) recorded gait parameters and muscle activity.
  • Center of Mass (CoM) deviation and self-reported discomfort were analyzed.

Main Results:

  • Increased leg flexor muscle activity before touchdown and lateral stabilizer activity during the swing phase were observed.
  • A significant increase in vertical CoM excursion, indicating a cautious gait, was noted.
  • The wave pattern was reported as most disruptive; colored patterns caused more discomfort than greyscale.

Conclusions:

  • Highly repetitive patterns impact the visuomotor system and gait control strategies.
  • Architectural design should carefully consider the use of repetitive patterns, especially colored ones, to avoid sensory burdens and ensure inclusivity.
