4EST Interview Questions and Answers

The least count of a Bernier caliper is typically 0.02 mm.

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

• Bernier calipers are commonly used in mechanical engineering and machining.

• The least count of a Bernier caliper can vary depending on the specific model and manufacturer.

• For example, some Bernier calipers may have a least count of 0.05 mm or 0.1 mm.

• To determine the least count of a specific Bernier caliper, consult the manufacturer's ...read more

Air is measured in units of pressure, volume, and density.

• Pressure is measured in units such as pascals (Pa), pounds per square inch (psi), or atmospheres (atm).

• Volume is measured in units such as cubic meters (m³), liters (L), or cubic feet (ft³).

• Density is measured in units such as kilograms per cubic meter (kg/m³) or pounds per cubic foot (lb/ft³).

5s,3r,4m is a code used in lean manufacturing for workplace organization and efficiency.

• 5s stands for Sort, Set in Order, Shine, Standardize, and Sustain

• 3r stands for Remove, Replace, and Repair

• 4m stands for Man, Machine, Material, and Method

• These codes are used to improve productivity, safety, and quality in the workplace

GD&T symbol stands for Geometric Dimensioning and Tolerancing symbol.

• GD&T symbols are used to specify the geometric requirements of a part or assembly.

• They include symbols for features such as flatness, perpendicularity, and concentricity.

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

• Examples of GD&T symbols include the concentricity symbol (a circle within a circle) and the perpendicularity symbol (a square with ...read more

Torque is a measure of the twisting force that causes rotation.

• Torque is a vector quantity that is calculated as the product of force and the distance from the axis of rotation.

• It is measured in units of Newton-meters (Nm) or pound-feet (lb-ft).

• Torque is important in many fields, including engineering, physics, and mechanics.

• Examples of torque include the force applied to a wrench to tighten a bolt, or the force applied to a car's wheels to make it move forward.

• Torque can be ...read more
