Measuring instruments are tools used to quantify physical quantities or properties.

• Measuring instruments are used to obtain accurate and precise measurements.

• They are commonly used in various fields such as physics, engineering, and manufacturing.

• Examples of measuring instruments include rulers, thermometers, voltmeters, and spectrometers.

Calibration is the process of adjusting or verifying the accuracy of an instrument or tool.

• Calibration ensures that an instrument or tool is accurate and reliable.

• It involves comparing the readings of the instrument to a known standard.

• Calibration is important in industries such as manufacturing, engineering, and healthcare.

• Examples of instruments that require calibration include thermometers, scales, and blood pressur

CNC stands for Computer Numerical Control. It is a manufacturing process that uses computerized machines to create precise and complex shapes.

• CNC machines are used in various industries such as aerospace, automotive, and medical.

• They are programmed using CAD (Computer-Aided Design) software to create 2D or 3D designs.

• CNC machines can cut, drill, mill, and shape materials such as metal, wood, and plastic.

• They offer high...read more

Young modulus is a measure of the stiffness of a material and is defined as the ratio of stress to strain.

• Young modulus is also known as modulus of elasticity or elastic modulus.

• It quantifies the ability of a material to deform under stress.

• Young modulus is a material property and varies for different materials.

• It is defined as the ratio of stress to strain within the elastic limit.

• Young modulus is expressed in units o...read more

The least count of a vernier caliper and a micrometer is the smallest measurement that can be accurately read.

• The least count of a vernier caliper is typically 0.02 mm or 0.001 inch.

• The least count of a micrometer is typically 0.01 mm or 0.001 inch.

• The least count is determined by the number of divisions on the main scale and the vernier scale.

• For example, if the main scale has 20 divisions and the vernier scale has 10...read more

The hydraulic pack pressure varies depending on the specific system and application.

• Hydraulic pack pressure is the force exerted by the hydraulic fluid in a hydraulic system.

• It is typically measured in pounds per square inch (psi) or bar.

• The pressure can vary based on the load requirements, system design, and component specifications.

• Higher pressure is often required for heavy-duty applications, while lower pressure ma...read more

2 phase and 3 phase are different types of electrical power distribution systems.

• 2 phase system has two conductors and produces a single alternating current waveform.

• 3 phase system has three conductors and produces three alternating current waveforms.

• 2 phase system is less common and used in older applications.

• 3 phase system is more efficient and widely used in industrial and commercial settings.

• 2 phase system requires...read more
