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

Quality Assurance (QA) ensures products meet specified requirements and standards through systematic processes and testing.

• QA involves processes that prevent defects in products, such as software or manufacturing.

• It includes activities like test planning, test case design, and execution to validate functionality.

• Example: In software QA, automated tests can be used to check for bugs before release.

• QA also focuses on continuous improvement, using metrics to enhance processes ov...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.

The 7 QC tools are basic statistical tools used in quality control to identify and solve problems.

ESIC contribution is a percentage of the employee's salary and is calculated on a monthly basis.

• ESIC contribution is 1.75% of the employee's salary

• The contribution is made by both the employer and the employee

• The contribution is calculated on a monthly basis

• The maximum limit for ESIC contribution is Rs. 21,000 per month

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
