Unformatted text preview: Biomechanics – Statics Review 1. What is a force? A FORCE is caused by the action of one body on the other body. Forces are described by: • Its point of application. • Its magnitude. • Its direction. 2. Forces are vectors which can be drawn to show direction (arrow) and magnitude (length). Scalars are quantities that are only represented by a number but not a direction (time, volume, mass). Vectors can be added by the parallelogram law: 3. Just as two vectors can be added to determine the resultant, a vector can be broken into two component vectors of which the choice is limitless. Special cases: (vector F known) (1) One component known: (2) Line of action of each components known: Magnitude of vector P&Q found by parallelogram law. 4. Breaking Down a vector in X and Y components 5. In a static system, the state of equilibrium is achieved by all resultant forces and moments being equal to zero....
