Ashok Leyland Diploma Trainee Engineer Interview Questions and Answers

Q1. What is gear working
Ans. 
Gear working refers to the process of gears transmitting motion and power between two rotating shafts.
• Gears have teeth that mesh together to transfer motion and power.

• The size and shape of the gears determine the speed and direction of rotation.

• Gears can be used to increase or decrease speed, change direction, or transfer power between shafts.

• Common examples of gear working include in vehicles (transmission gears) and

Q2. What is 4 stock engine and 2 stock engine
Ans. 
4 stroke engine completes four separate strokes to generate power, while 2 stroke engine completes two strokes.
• 4 stroke engine has separate intake, compression, power, and exhaust strokes

• 2 stroke engine combines intake/compression and power/exhaust strokes

• Examples: Most cars use 4 stroke engines, while some motorcycles use 2 stroke engines

Q1. Gear ratio of multiple transmissions
Ans. 
Gear ratio of multiple transmissions is the product of individual gear ratios.
• Gear ratio is the ratio of the number of teeth on the driven gear to the number of teeth on the driving gear.

• In multiple transmissions, the output of one transmission becomes the input of the next transmission.

• The gear ratio of multiple transmissions is the product of individual gear ratios.

• For example, if the first transmission has a gear ra...read more

Q2. Reasons behind multiple gear ratios
Ans. 
Multiple gear ratios allow for efficient power transfer and improved performance in different driving conditions.
• Different gear ratios are needed for different driving conditions, such as acceleration, cruising, and climbing hills.

• Lower gear ratios provide more torque for acceleration and climbing hills, while higher gear ratios provide better fuel efficiency during cruising.

• Multiple gear ratios allow for a wider range...read more

Q3. Thread designing and their strength
Ans. 
Thread designing involves determining the size, pitch, and shape of the thread to ensure proper strength and functionality.
• Thread size and pitch must be chosen based on the application and load requirements.

• Thread shape can affect the strength and ease of assembly.

• Thread strength can be increased through the use of materials with higher tensile strength.

• Thread engagement length should be sufficient to prevent stripping...read more
