Shriram Pistons & Rings Diploma Trainee Engineer Interview Questions and Answers

Bearings are used to reduce friction between two moving parts. Metal type is important for bearing performance.

• Metal type affects bearing strength, durability, and resistance to corrosion.

• Common bearing metals include steel, bronze, and ceramic.

• Steel bearings are strong and durable, but can corrode in certain environments.

• Bronze bearings are self-lubricating and resistant to corrosion, but not as strong as steel.

• Cerami...read more

Two-stroke engines have power strokes every revolution, while four-stroke engines have power strokes every other revolution.

• Two-stroke engines have a simpler design with fewer moving parts.

• Four-stroke engines are more fuel efficient and produce less pollution.

• Two-stroke engines are commonly used in small power tools and motorcycles.

• Four-stroke engines are typically found in cars, trucks, and larger machinery.

Cycle time is the total time taken to complete a process or task from start to finish.

• Cycle time is a key metric in process improvement and efficiency analysis.

• It helps in identifying bottlenecks and areas for improvement in a process.

• For example, in manufacturing, cycle time can refer to the time taken to produce one unit of a product.

• Reducing cycle time can lead to increased productivity and cost savings.

Line balancing is the process of assigning tasks to workstations in a way that evens out the workload and maximizes efficiency.

• Involves distributing work evenly among workstations

• Helps in reducing idle time and bottlenecks

• Improves productivity and efficiency

• Example: In a manufacturing plant, line balancing ensures each workstation has a similar amount of work to do

Thermodynamics laws, types of gears and bearings

• Thermodynamics laws include the first law (conservation of energy), second law (entropy always increases), and third law (absolute zero is unattainable)

• Types of gears include spur, helical, bevel, worm, and rack and pinion

• Types of bearings include ball bearings, roller bearings, and plain bearings

• Gears and bearings are commonly used in machinery and mechanical systems
