How does 2nd gear create more thrust than 1st gear?
Let’s analyze a vehicle parallel to velocity and forces applying on it.
The 1st gear has a maximum velocity value after which you can’t accelerate more. It means that thrust force on wheels generated ...

Why is the torque of an ICE low at low rpms?
Let us consider a basic 4-stroke single cylinder, direct port fuel injected naturally aspirated engine which is given a constant throttle.
Now, why does it produce very low torque at low rpms, meaning ...
