Al-shahba Holding Interview Questions and Answers

The least count of vernier and micrometer depends on their design and specifications.

• The least count of a vernier caliper can range from 0.02 mm to 0.05 mm.

• The least count of a micrometer can range from 0.001 mm to 0.01 mm.

• The least count is the smallest measurement that can be read on the instrument.

• The least count is determined by the number of divisions on the scale and the pitch of the screw.

• Higher precision instruments have smaller least counts.

IS 2062 is a standard for hot rolled steel used in general structural purposes.

• IS 2062 is a standard set by the Bureau of Indian Standards (BIS)

• It specifies the requirements for hot rolled steel used in general structural purposes

• The steel must have a minimum yield strength of 250 MPa

• It covers steel grades from E 250 to E 650

• IS 2062 is commonly used in the construction industry in India

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

• Tolerance is used to determine if a product or process meets the required standards.

• It allows for small deviations or errors within a specified limit.

• Tolerance is often expressed as a plus or minus value around a target measurement.

• For example, if the tolerance for a length measurement is ±0.1mm, it means the actual length can vary by up to 0.1mm from the target value.

Yes, UT stands for Ultrasonic Testing which is a non-destructive testing method used to detect flaws or defects in materials.

• UT uses high-frequency sound waves to penetrate materials and detect internal flaws or defects.

• It is commonly used in industries such as aerospace, automotive, and manufacturing.

• UT can detect cracks, voids, and other defects that may not be visible to the naked eye.

• It is a valuable tool for ensuring the quality and safety of materials and products.

• UT ca...read more

A calliper is a measuring tool used to measure the distance between two opposite sides of an object.

• Callipers can be either digital or analogue.

• They are commonly used in manufacturing and engineering to ensure precise measurements.

• Examples of objects that can be measured with callipers include pipes, bolts, and bearings.

A lathe machine is a tool that rotates a workpiece on its axis to perform various operations such as cutting, drilling, and sanding.

• Lathe machines are used to shape and form metal, wood, and other materials.

• They can be used to create cylindrical shapes, tapered shapes, and threaded surfaces.

• Lathe machines can also be used for facing, boring, and turning operations.

• Examples of products made using lathe machines include crankshafts, camshafts, and gun barrels.

GD&T symbols are geometric dimensioning and tolerancing symbols used to specify and control the form, orientation, and location of features on a part.

• GD&T symbols are used to ensure that parts are manufactured to the correct specifications and fit together properly.

• Some common GD&T symbols include concentricity, perpendicularity, and position.

• GD&T symbols are often used in engineering drawings and blueprints.

• GD&T symbols can be complex and require specialized training to inte...read more
