What is mechanics?
The science which describes and predicts the conditions or motion of bodies under the action of forces.
Deals with the bodies at rest. (MARE205)
Deals with the bodies in motion. (MARE206)
Strength of Materials
Different types of loading conditions and stress analysis.
Newton's First Law
Newton's Second Law
Newton's Third Law
for every action there is an equal and opposite reaction
Newton's Law of Gravitation
when all of the forces converge at one point
When all of the forces do not converge on a common point.
Law of Sines
sinA/a = sinB/b =sinC/c
Law of Cosines
a² = b² + c² - 2bc cos α
b² = a² + c² - 2ac cos β
c² = a² + b² -2ab cos γ
