Newton's law refers to three laws of motion that describe the relationship between a body and the forces acting upon it.

• Newton's first law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity, unless acted upon by a net external force.

• Newton's second law states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass.

• Newton's third...read more

There are three types of flames in gas welding - neutral, oxidizing, and carburizing.

• Neutral flame has equal amounts of oxygen and acetylene and is used for general welding.

• Oxidizing flame has more oxygen than acetylene and is used for cutting and brazing.

• Carburizing flame has more acetylene than oxygen and is used for hardening steel.

Knocking is an abnormal combustion phenomenon in internal combustion engines.

• It occurs when the air-fuel mixture in the cylinder detonates spontaneously instead of burning smoothly.

• It causes a knocking or pinging sound and can damage the engine if left unchecked.

• It can be caused by factors such as low octane fuel, incorrect ignition timing, or carbon buildup in the engine.

• It can be prevented by using high octane fuel, maintaining the engine properly, and adjusting the ignitio...read more

There are several types of welding, including MIG, TIG, Stick, and Flux-Cored welding.

• MIG (Metal Inert Gas) welding uses a wire electrode and a shielding gas to join two pieces of metal together.

• TIG (Tungsten Inert Gas) welding uses a tungsten electrode and a shielding gas to create a precise and clean weld.

• Stick welding, also known as Shielded Metal Arc Welding (SMAW), uses a consumable electrode coated in flux to create a strong bond between two pieces of metal.

• Flux-Cored w...read more
