Daimler India Commercial Vehicles Graduate Trainee Interview Questions and Answers

Torque formula is used to calculate the rotational force acting on an object.

• Torque = Force x Distance

• The SI unit of torque is Newton-meter (Nm)

• Torque is a vector quantity, having both magnitude and direction

• Example: If a force of 10 N is applied at a distance of 5 meters from the pivot point, the torque would be 50 Nm

AEN stands for Assistant Engineer

• AEN stands for Assistant Engineer

• AEN is a common abbreviation used in engineering and technical fields

• Example: AEN John Smith is the Assistant Engineer responsible for the project

A synchronous motor is a type of AC motor where the rotation of the shaft is synchronized with the frequency of the supply current.

• Uses electromagnets to create a rotating magnetic field

• Requires a constant supply of AC power to maintain synchronization

• Commonly used in applications where precise speed control is required, such as in industrial machinery

• Examples include synchronous motors used in clocks, turntables, and

Pistons are typically made from aluminum alloy, cast iron, or steel.

• Aluminum alloy is lightweight and commonly used in high-performance engines.

• Cast iron is durable and often used in diesel engines.

• Steel pistons are strong and used in heavy-duty applications.

The crank in an engine converts the linear motion of the pistons into rotational motion to drive the vehicle.

• The crankshaft is connected to the pistons through connecting rods, allowing the up and down motion of the pistons to be converted into rotational motion.

• The crankshaft rotates, transferring power to the transmission and ultimately to the wheels of the vehicle.

• The design of the crankshaft determines the engine's...read more
