Integration by substitution is a method used to simplify the integration process by transforming the original integral into a simpler one through a change of variables. This technique is particularly useful when dealing with composite functions, as it can reduce complex integrals to basic forms that are easier to evaluate.

Torque transfer is the process by which rotational force is distributed from one part of a mechanical system to another, ensuring optimal performance and efficiency. It is crucial in applications like automotive drivetrains, where it impacts traction, stability, and fuel efficiency by managing how power is delivered to the wheels.

Torque vectoring helps cars turn corners better by sending different amounts of power to each wheel. It's like when you push a toy car with one hand harder than the other to make it turn.
Concept
All-wheel drive (AWD) refers to a drivetrain system that powers all four wheels of a vehicle simultaneously, optimizing traction and handling in various driving conditions. Unlike four-wheel drive systems which are typically designed for off-road use, AWD systems are generally better suited for on-road performance and are often found in cars, crossovers, and SUVs.

Torque distribution refers to the process of managing the way torque is apportioned to different wheels or axles of a vehicle, impacting traction and handling performance. Modern systems automatically adjust torque distribution to optimize stability and efficiency based on driving conditions and driver inputs.

A drive mechanism is a system designed to transmit and control the transfer of power from a source, such as an engine or motor, to a device or component requiring movement.
