Mechanics is, like Webster 1913 defines, the Science of Body Movements in Space and Time.
But how to get along with them in School, University or Work?

Of course, you can carry a Formulary with you all the time. Then, by another way of Murphy's Law, you'll always forget it when you really need it. Never mind, all you need is already there. The solution for a Mechanical Problem can be found by performing the following Steps:

  1. Collect all Informations you've got about the Problem, like Mass, Speed, Energy, etc.
  2. Read the Question properly, if there is one; if not, ask yourself what you want to find out.
  3. Look at the Measure Units of the Informations available and the value your Solution should present, like Mass (kg), Speed (km/h, mp/h, m/sec), Time (h, min, sec), Force (N=kg*m/sec^2), Energy (Nm=kg*m^2/sec^2) and so on. Did you notice that every of those Units already represents a Formula?
  4. Now all you got to do is find out how the Informations already given have to fit into that Formula.
  5. Fill in the Informations and use your Mathematic Skills to solve the Equation.

Problem solved.

Me*chan"ics (?), n. [Cf. F. m'ecanique.]

That science, or branch of applied mathematics, which treats of the action of forces on bodies.

⇒ That part of mechanics which considers the action of forces in producing rest or equilibrium is called statics; that which relates to such action in producing motion is called dynamics. The term mechanics includes the action of forces on all bodies, whether solid, liquid, or gaseous. It is sometimes, however, and formerly was often, used distinctively of solid bodies only: The mechanics of liquid bodies is called also hydrostatics, or hydrodynamics, according as the laws of rest or of motion are considered. The mechanics of gaseous bodies is called also pneumatics. The mechanics of fluids in motion, with special reference to the methods of obtaining from them useful results, constitutes hydraulics.

Animal mechanics Physiol., that portion of physiology which has for its object the investigation of the laws of equilibrium and motion in the animal body. The most important mechanical principle is that of the lever, the bones forming the arms of the levers, the contractile muscles the power, the joints the fulcra or points of support, while the weight of the body or of the individual limbs constitutes the weight or resistance. -- Applied mechanics, the principles of abstract mechanics applied to human art; also, the practical application of the laws of matter and motion to the construction of machines and structures of all kinds.
