Normal and Tangetial Components: Problem Solving

743
Consider a man with a mass of 70 kg seated in a chair connected to a pin support through a member BC. If the man maintains an upright position, the task is to determine the horizontal and vertical reactions of the chair on the man when the member makes a 45° angle with the horizontal. At this moment, the man has a speed of 5 m/s, increasing at a rate of 1 m/s².

Self-Locking Screw01:16

Self-Locking Screw

2.9K
A square-threaded screw jack is a mechanical device widely used for lifting heavy loads or applying considerable force. One of the key features that can make a screw jack more effective and reliable is its self-locking capability.
A square-threaded screw jack carrying a load is considered self-locking if the screw retains its position even after the moment applied to it is removed.

Unsymmetric Bending - Angle of Neutral Axis01:15

Unsymmetric Bending - Angle of Neutral Axis

1.0K
Unsymmetrical bending occurs when a structural member is subjected to bending moments in a plane that does not align with the member's principal axes. This scenario typically arises in beams and other structural components when loads are applied at non-ideal angles, introducing complexities in stress analysis.
When a bending moment is applied at an angle θ concerning the vertical axis of a symmetrical member, it can be resolved into components along the member's principal...

Design of Prismatic Beams for Bending

674
The design of prismatic beams, structural elements with a uniform cross-section, focuses on ensuring safety and structural integrity under load. The design process begins by determining the allowable stress, either from material properties tables, or by dividing the material's ultimate strength by a safety factor. This safety factor is essential for accommodating uncertainties, and varies depending on the material—timber, steel, or concrete—with each having unique strength and...

Design Example: Traverse Angle Computations

453
Traverse angle computations are a critical component of surveying, used to compute the internal angles within a closed traverse. A traverse consists of a series of connected lines forming a closed loop, often used for land boundary delineation or mapping. Calculating the internal angles ensures accuracy in the traverse geometry and is essential for checking survey data integrity.The process begins with known azimuths and bearings of the traverse sides. Internal angles at each vertex are...

Area of Science:

  • Rehabilitation Engineering
  • Biomedical Design
  • Human Factors Engineering

Background:

  • Manual wheelchair users require adaptive seating solutions to maintain comfort, support, and an active lifestyle.
  • Existing backrest designs may not adequately address the dynamic needs of users during daily activities and pressure relief maneuvers.

Purpose of the Study:

  • To design and evaluate a final prototype of angle-adjustable backrest hardware for manual wheelchairs.
  • To assess user feedback on the comfort, support, adjustability, and aesthetics of the prototype.

Main Methods:

  • An iterative design protocol was followed, culminating in ISO standards testing of the prototype.
  • A focus group of 8 independent manual wheelchair users evaluated the prototype using a questionnaire on its performance and usability.

Main Results:

  • The backrest prototype successfully passed ISO testing standards.
  • Focus group participants reported positive overall impressions, particularly regarding comfort, support, and adjustability.
  • Key areas for improvement included the string mechanism and the ease of reaching the adjustment controls.

Conclusions:

  • The angle-adjustable backrest prototype shows promise for enhancing manual wheelchair user experience.
  • Further design iterations are needed to optimize operation and usability for improved user satisfaction.
  • The adjustable backrest has the potential to support active lifestyles and improve balance control during pressure relief activities for manual wheelchair users.
