1. Kinematics of Mechanism: the study of motion without regard to forces That is about motion of the components and the basic geometry of the mechanism, and is not concerned with the forces which cause or affect the motion all the components of the mechanism are, in general considered rigid member 2. Kinetics or Dynamics of Mechanisms: the study of forces on the system in motion

The Fourth method: Definition a dictionary will give you two different definitions of the word definition: ( \a statement of what a thing is\and(2)a\a statement or explanation of what a word or phrase means or has meant. \ In the strict sense a definition as we shall use the word here is not of a thing. but of a word or of a process The process of making a definition is not, however, a mere game of words. It is clear that we cannot make a usefu

The zeroth law of thermodynamics: The expression of the fundamental experiment fact. The first law of thermodynamics: The a statement of conservation of energy for pure thermodynamic system. The second law of thermodynamics: Why we need the second law of thermodynamics?
