What is the requirement of torque?

Torque has 2 main components: load torque and acceleration torque. Load torque is the amount of torque constantly required for application and includes friction load and gravitational load. Acceleration torque is the torque required just for the maximum acceleration and deceleration rate for the load.

What is power and torque in car?

Torque refers to the capacity to do work, while power is the rate of completing work in a given amount of time. The primary use of torque is to make the car accelerate in the initial stages of movement, while the horsepower determines the rate of the acceleration of the vehicle.

How much power is required to run a car?

There is a direct conversion between horsepower and watts: 745.7 watts is 1 horsepower. Car motors for modern vehicles range from about 50 horsepower to 500 horsepower or more. An average medium size family car might have a 150 HP motor. To duplicate that with an electric motor you would need 111,855 watts of power.

Why is torque important in a car?

Torque is a crucial part of generating power from a car’s engine, as it represents the load an engine can handle to generate a certain amount of power to rotate the engine on its axis. Multiply this torque force (in lb-ft.) by the axis’s rotational speed per minute (RPM) and you get the engine’s power output.

How is power and torque related?

Torque is the rotational equivalence of linear force. Power is work done in a time interval. The relation between torque and power is directly proportional to each other. The power of a rotating object can be mathematically written as the scalar product of torque and angular velocity.

Which is important torque or power?

Horsepower equals torque multiplied by rpm, divided by a constant. Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms. This is also why people talk about “low-end torque” being important for better power at slower speeds.

Which Gear has more torque?

More torque is produced by lower gears. Power remains essentially constant through all gears, however the product of torque and speed is power… so as you change to lower gears delivering more torque, you will operate at lower rotational speeds. Higher gears yield less torque but more rotational speed.
