Basic Concept

Basic Concept

Engineering mechanics is a branch of engineering that studies motion and the forces acting on objects. It is a fundamental subject and forms the basis of many other engineering disciplines. Length, time, mass, and force are some basic concepts in engineering mechanics.
Length, which measures the distance traveled by an object, is a fundamental concept in engineering mechanics. We use coordinates relative to a reference point to describe the distance. Length not only helps to describe the...

An Introduction to Mechanics

An Introduction to Mechanics

Humans have been making ships, shelters, pyramids, weapons, agricultural equipment, and many more items without recording the process or theory behind them for centuries. It would be challenging to document the evolution of mechanics from its origin to the present.
According to records, the history of mechanics starts with Aristotle (384–322 BC). He related mechanics to physical theory, aiming for a universal synthesis.
Newton defined mechanics as the branch of physical science that studies the...

Machines: Problem Solving II

Machines: Problem Solving II

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. Consider a lifting tong carrying a 100 kg load. It comprises movable sections DAF and CBG linked together with member AB.

Free-body Diagrams: Problem Solving

Free-body Diagrams: Problem Solving

Free-body diagrams are essential tools for physicists and engineers studying the motion of objects. Free-body diagrams are graphical representations of the object or system under consideration, and they focus solely on the essential forces acting on the object. This tool helps break down complex problems into simpler models that are easier to understand and solve.
For example, consider a block with a mass of 10 kg released on an inclined plane at an angle of 30° to the horizontal, where the...

Problem Solving in Statics

Problem Solving in Statics

Problem-solving in statics is a crucial aspect of engineering and physics that involves resolving issues associated with bodies in a state of equilibrium. In most cases, problem-solving requires several steps to achieve an accurate result. These steps are crucial to ensuring that the solution is accurate and practical.
The physical situation and mathematical modeling must be considered; however, it is challenging to represent all physical situations using mathematical modeling. With the help of...

Steps for Free-Body Diagram

Steps for Free-Body Diagram

When it comes to studying the behavior of objects in mechanics, one of the most important tools available is the free-body diagram. Consider a simple example of a system of two blocks coupled by a massless string over a frictionless pulley. Block 1 is sliding over a table pulled by block 2 as block 2 falls under gravity.
To find the acceleration of the system, it is first necessary to calculate the net force on the system. In order to accomplish this, a free-body diagram can be created to...

Area of Science:

Biomechanical analysis
Occupational health for manual therapists

Background:

Manual therapy practitioners' economic viability depends on treatment volume.
Practitioner fatigue and injury can lead to career termination.
Diverse postures are used in manual therapy, impacting practitioner strain.

Purpose of the Study:

To identify an optimal force application method for manual therapy.
To maximize client benefit while minimizing practitioner strain.
To compare the biomechanical effects of "poor" versus "best" body mechanics.

Main Methods:

Computer modeling of practitioner joint biomechanics (elbow, shoulder, hip, knee, ankle).
Field study with 18 massage practitioners assessing maximal force capability.
Quantified comparison of "Improper" and "Proper" body mechanics using a digital palm force gauge across various application heights.

Main Results:

Significant differences were observed between "Improper" and "Proper" body mechanics.
Correct body mechanics demonstrably reduce strain and effort for the practitioner.
The findings indicate a substantial impact on practitioner health and well-being.

Conclusions:

Optimal force application techniques are crucial for manual therapists.
Implementing correct body mechanics is vital for practitioner sustainability and preventing career-ending injuries.
This research supports the adoption of evidence-based biomechanical practices in manual therapy.
