Introduction to Statics

Forces. Systems of units: units, mass, force, weight. Forces and reactions. Representation of a force by a vector. Forces in the body such as the joints. Kinematic and kinetics in 2D.

Vector Algebra

Graphical addition, parallelogram of forces. Equilibrant and resultantTriangle of forces. Resolving forces into orthogonal axis. Mathematical addition of forces.Ground reaction force.

Free body diagrams

Free body diagrams, force analysis with a single muscle (e.g. glenohumeral joint). Practical problems of joints such as the hip, elbow and knee.

Newton’s laws of Motion

Three laws of motion & biomechanical applications.

Moment

Moment, Effects of a force; turning effect; moments, resultant moment, balancing moments; Calculation of forces in joints and brackets. Principle of moments to calculate the reactions of beams. Calculation of the Centre of gravity of various laminae. Measurement of the Centre of gravity of the human body - using the method of sections.

Linear Motion

Motion in a straight line; distance and speed, concept of scalars and vectors; velocity and acceleration; equations of motion (derivation); acceleration of a falling body. Projectiles.

Friction

Friction force, limiting friction force; law of friction, coefficient of friction (static & dynamic); friction on a horizontal plane; friction on a inclined plane. Friction within a healthy joint versus and deseased joint.
