LMW Textile Machinery Division Interview Questions, Process, and Tips

Q1. How to design a Shaft.
Ans. 
Designing a shaft involves determining the material, dimensions, and manufacturing process to ensure strength and durability.
• Consider the material properties such as strength, stiffness, and corrosion resistance.

• Calculate the required dimensions based on the load, speed, and operating conditions.

• Select the appropriate manufacturing process such as machining or forging.

• Ensure proper alignment and support to prevent bend

Q2. Explain about gears
Ans. 
Gears are mechanical components used to transmit motion and power between rotating shafts.
• Gears have teeth that mesh together to transmit motion

• They can change the speed, torque, and direction of rotation

• Common types include spur gears, helical gears, and bevel gears

• Gears are often used in machinery such as cars, bicycles, and industrial equipment

Q1. Stress Strain diagram
Ans. 
Stress Strain diagram shows the relationship between stress and strain in a material.
• Shows how a material deforms under stress

• Helps determine material properties like yield strength and modulus of elasticity

• Can be used to compare different materials' behavior under load

Q2. Pressure vs load
Ans. 
Pressure is force applied over an area, while load is the weight supported by a structure or material.
• Pressure is force applied perpendicular to a surface, measured in units like psi or Pa.

• Load is the weight supported by a structure or material, measured in units like pounds or newtons.

• Pressure can cause deformation or stress in a material, while load determines the strength needed to support it.

• Examples: A hydraulic p...read more

Q3. What is Bearing
Ans. 
A bearing is a machine element that allows one part to bear another part's load while reducing friction between the two parts.
• Bearing helps in reducing friction between moving parts

• They support radial and axial loads

• Common types include ball bearings, roller bearings, and plain bearings

Q1. Beam and its types
Ans. 
A beam is a structural element that carries load primarily in bending. Types include cantilever, simply supported, fixed, and continuous beams.
• Beams are horizontal or inclined structural members that support loads applied perpendicular to their longitudinal axis.

• Types of beams include cantilever beams (supported at one end), simply supported beams (supported at both ends), fixed beams (supported at both ends with addit...read more

Q2. Stress strain curve was asked to draw
Ans. 
Stress-strain curve shows the relationship between stress and strain in a material.
• The curve has three regions: elastic, plastic, and fracture.

• Elastic region shows linear relationship between stress and strain.

• Plastic region shows non-linear relationship between stress and strain.

• Fracture region shows the point at which the material breaks.

• The slope of the curve in the elastic region is called Young's modulus.

• The area ...read more
