Concept of Mechanics

Concept of Mechanics
What is Mechanical Engineering? Mechanical engineering is the discipline that applies the principles of engineering, physics, and materials science for the design, analysis, manufacturing, and maintenance of mechanical systems.

Static Mechanic
Statics is the branch of mechanics that is concerned with the analysis of loads, force and torque, acting on physical systems.

Dynamic Mechanic


Dynamics is a branch of applied mathematics concerned with the study of forces and torques and their effect on motion, as opposed to kinematics, which studies the motion of objects without reference to its causes. Isaac Newton second law of motion.

Kinematics
is the branch of classical mechanics which describes the motion of points, bodies (objects) and systems of bodies (groups of objects) without consideration of the causes of motion. So you only have velocities and accelerations without the forces/torques which creates the motion.

Kinetics
is a term for the branch of classical mechanics that is concerned with the relationship between the motion of bodies and its causes, namely forces and torques. So here you have both velocities, accelerations and the forces which creates the motion.

 * Mechanics
 * 1) Statics.
 * 2) Dynamics.
 * 3) Mechanics of Materials.
 * 4) Fluid Mechanics.
 * 5) Kinematics.
 * Structural Analysis:Structural analysis is the branch of mechanical engineering (and also civil engineering) devoted to examining why and how objects fail and to fix the objects and their performance.
 * Mechatronics: Mechatronics is the combination of mechanics and electronics. It is an interdisciplinary branch of mechanical engineering.
 * Thermodynamics:Thermodynamics is an applied science used in several branches of engineering, including mechanical and chemical engineering. At its simplest, thermodynamics is the study of energy, its use and transformation through a system.

Human Thermal Regulations
Thermal Receptors A thermoreceptor is a non-specialised sensory receptor, or more accurately the receptive portion of a sensory neuron, that codes absolute and relative changes in temperature, primarily within the innocuous range.

Light in Human body

 * Retina Eye:Light sensitivity The retina is constituted by several layers of different cell types.Rods and cones are photoreceptors and light-gathering cells.

Joints
Synovial joints are the most commonly occurring type of joint, which also produce the greatest range of movements. The movements created at synovial joints allow us to do everyday activities like walking, running, writing and typing.

Nerve Cells
Neurons are nerve cells that transmit nerve signals to and from the brain at up to 200 mph. The neuron consists of a cell body (or soma) with branching dendrites(signal receivers) The synapse contains a small gap separating neurons. Information from one neuron flows to another neuron across a synapse. Move information from neurotransmitter to receptors
