This article is a continuation of the common mechanical vocabulary used in engineering and machinery. It covers various technical terms that are essential for understanding the fundamentals of mechanical systems and materials. Whether you're an engineer, student, or enthusiast, this list provides valuable insight into key terminology used in the field.
Bunsen Burner – A gas-powered device used for heating and sterilization in laboratories.
Intrinsic Semiconductor – A pure semiconductor material with no impurities, such as silicon or germanium.
Flip-Flop – A digital circuit used to store binary data, commonly found in digital electronics.
Normalizing – A heat treatment process used to improve the microstructure and mechanical properties of metals.
Forward Bias – A condition in which a diode allows current to flow by applying voltage in the correct direction.
Orthographic Projection – A method of representing three-dimensional objects on a two-dimensional plane using multiple views.
Spur Gear – A type of gear with straight teeth used to transmit rotational motion between parallel shafts.
Cast Iron – A brittle alloy of iron and carbon, known for its excellent casting properties.
Limestone – A sedimentary rock composed mainly of calcium carbonate, often used in construction.
Quartz Crystal Oscillator – An electronic component that uses a quartz crystal to generate a stable frequency signal.
Asbestos – A naturally occurring fibrous mineral once widely used for insulation, now restricted due to health risks.
Oscilloscope – An electronic test instrument used to observe and analyze electrical signals over time.
Copolymer – A polymer made from two or more different monomers, offering improved properties compared to homopolymers.
Covalent Bond – A chemical bond formed by the sharing of electron pairs between atoms.
Resonance – A phenomenon where a system oscillates at greater amplitude when the frequency of an external force matches its natural frequency.
Printed Circuit Board (PCB) – A board used to mechanically support and electrically connect electronic components.
Alloy Tool Steel – A type of steel containing elements like chromium, vanadium, or tungsten, designed for high strength and wear resistance.
Tempering – A heat treatment process used to reduce brittleness and increase toughness in hardened metals.
Multi-Point Cutting Tool – A cutting tool with multiple cutting edges, often used in machining operations.
Porous Plastic – A type of plastic with many small holes, commonly used in packaging and cushioning applications.

A carriage Bolt has a square shoulder under a rounded head which resists turning when the nut is tightened or removed. They are good for wood-to-wood connections when the head may not be accessible for tightening. They may be used in the construction of docks, swing sets and decks as well as Other surfaces where a smooth finish is needed.
