Commonly used tools to shape wood for various types of joints by driving in and driving out nail involve cutting and smoothening of wood surfaces. A broad classification of tools used in the wood working or carpentry shop are measuring and marking tools, supporting and holding tools, cutting tools, striking tools and miscellaneous tools. Most of commonly used tool and ... Read More »

Air-Conditioning

Air-conditioning is a process that simultaneously conditions air; distributes it combined with the outdoorair to the conditioned space; and at the same time controls and maintains the required space’s temperature,humidity, air movement, air cleanliness, sound level, and pressure differential within predetermined limits for the health and comfort of the occupants, for product processing, or both. The acronym HVAC&R stands for ... Read More »

Air-Conditioning Systems

An air-conditioning or HVAC&R system consists of components and equipment arranged in sequentialorder to heat or cool, humidify or dehumidify, clean and purify, attenuate objectionable equipment noise,transport the conditioned outdoor air and recirculate air to the conditioned space, and control and maintainan indoor or enclosed environment at optimum energy use. The types of buildings which the air-conditioning system serves can ... Read More »

Motivating examples and major applications

A dynamical system is a mathematical model of a system evolving in time. Most models in mathematical physics are dynamical systems. If the system has only a finite number of `state variables’, then its dynamics can be encoded in an ordinary differential equation (ODE), which expresses the time derivative of each state variable (i.e. its rate of change over time) ...

Effect of Impurties on Steel

The following are the effects of impurities like silicon, sulphur, manganese and phosphorus on steel. 1. Silicon: The amount of silicon in the finished steel usually ranges from 0.05 to 0.30%. Silicon is added in low carbon steels to prevent them from becoming porous. It removes the gases and oxides, prevent blow holes and thereby makes the steel tougher and ... Read More »

Mechanical Engineering (Definition)

Mechanical engineering is a discipline of engineering that applies the principles of physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems.

Newtons First Law of Motion

Definition:It states ” Every body continues in its state of rest or of uniform motion in a straight line, unless acted upon by some external force.” This is also known as law of Inertia. Facebook Comments Read More »

Law of Inertia

Definition:It states ” Every body continues in its state of rest or of uniform motion in a straight line, unless acted upon by some external force.” This is also known as law of Inertia. The Inertia is that property of a matter, by virtue of which a body can not move of itself, nor change the motion imparted to it. ... Read More »
