Violeta Interview Questions and Answers

Angle projection is a method of representing a 3D object on a 2D plane using angles.

• It involves projecting the object onto a plane at a specific angle.

• The angles used in the projection are typically 45 degrees or 30 degrees.

• This method is commonly used in engineering and architecture for creating technical drawings.

• It helps to show the true shape and size of the object in a clear and concise manner.

• Examples of angle projections include isometric, dimetric, and trimetric proje...read more

Vernier Caliper and Micrometer least count

• Least count of Vernier Caliper is 0.02 mm and Micrometer is 0.01 mm

• Least count is the smallest measurement that can be read on the instrument

• Vernier Caliper is used to measure length, diameter, depth, and thickness

• Micrometer is used to measure small distances, thickness, and diameters

Manufacturing process involves converting raw materials into finished products through various steps and techniques.

• Manufacturing process starts with the design of the product

• Raw materials are sourced and inspected for quality

• Materials are processed through various methods like casting, molding, machining, etc.

• Quality control checks are performed at different stages

• Finished products are packaged and distributed to customers

Tolerance refers to the acceptable range of variation in a measurement or specification.

• Tolerance is important in manufacturing to ensure that products meet the required specifications.

• It is usually expressed as a range of values or as a maximum deviation from a target value.

• For example, if a part is supposed to be 10 cm long with a tolerance of +/- 0.1 cm, it means that the actual length can be anywhere between 9.9 cm and 10.1 cm.

• Tolerance can also refer to the ability to ac...read more

Degree of freedom refers to the number of independent variables or parameters that can vary in a system.

• Degree of freedom is the number of variables that can be changed independently without affecting the overall system.

• In mechanics, a rigid body in a plane has 3 degrees of freedom - two translations and one rotation.

• In thermodynamics, a simple compressible substance has 2 degrees of freedom - temperature and pressure.

• In statistics, degrees of freedom are used in hypothesis t...read more

Micrometre is a precision measuring instrument used to measure small distances accurately.

• Micrometre consists of a stationary anvil and a movable spindle.

• The object to be measured is placed between the anvil and spindle, and the spindle is turned to make contact with the object.

• The measurement is read from the scale on the sleeve and thimble of the micrometre.

• Micrometres are commonly used in engineering and manufacturing for precise measurements.

• Example: Measuring the thickne...read more
