Introduction ( history) of solar panels: Types of Solar Panels: Alexandre Edmond Becquerel is considered to be the father of solar panels, having discovered how electricity is made from sunlight in 1839. His research created a way to build solar plants that heated water to make steam for electric machines during the Industrial Revolution Becquerel’s…

An overview: The refrigeration cycle is a simple yet incredibly smart and useful process. In its simplest form, the refrigeration cycle consists of just 4 introductory factors to complete the circuit A compressor. A condenser. An expansion device. An evaporator. That is it. Well, that is it, we also need a coolant to circulate…

Introduction to vapor compression refrigeration: The compression refrigeration cycle consists of circulating a liquid refrigerant through four stages of an unrestricted system. As the refrigerant circulates through the system, it alternatively compresses and expands, changing its state from liquid to vapor. As the refrigerant changes state, the system absorbs and expels heat, reducing the temperature…
Ultrasonic machining is a subtractive manufacturing process that removes material from the surface of a part through low-amplitude, high-frequency vibrations of a tool against the material surface in the presence of fine abrasive particles. Ultrasonic vibration machining physically operates through the mechanism of microchip or erosion on the surface of the workpiece. As the abrasive…

Law of Conservation of Energy: The Law of Conservation of Energy states that “Energy cannot be created nor destroyed in an isolated system; it can only be transformed from one form to another or transferred between objects”. This principle is critical for understanding numerous natural phenomena, providing the foundation for various scientific theories and technological…

LIMITATIONS OF THE FIRST LAW OF THERMODYNAMICS The first law of thermodynamics based on the law of conservation of energy has proven to be a powerful tool for thermodynamic analysis. But over the time that it has been applied to some real systems, it has been observed that, theoretically, the first law holds for processes…

Components of the internal combustion engine: An internal combustion engine is the source of “power” in a car. Internal combustion engines can be broadly classified based on their operation, number of cylinders, and the fuel used. Depending on your operation, the engine can be either two-stroke or four-stroke. In two-stroke engines, the work cycle is…

Although iron and steel are the most common and important materials that we have to deal with, there are other metals used in the workshop that you will need to have some knowledge of. The main pure metals from the non-ferrous group that the reader will have to deal with are aluminium, copper, lead, tin…

All of the workshop engineer’s energy is directed towards some aspect of changing the shape of the metal, and we will now discuss the general issue of hot and cold working. Cold working means subjecting the metal to forces that cause it to undergo plastic deformation when it is below the lowest critical temperature (perlite…
