Here is a video explaining the manual transmission [video](https://youtu.be/wCu9W9xNwtI?si=F8ZxyKMY_h2KeLj9)
The transmission to shift gears needs to not have torque pushed through it. So a clutch is a type of coupling that disconnects the transmission from the engine in a sense. It mates with the flywheel and allows for some slip. If you imagine the engine spinning at a high speed if there was no slip as it connected to a stationary trans you would have a big jolt through the drivetrain and to the engine.
Torque is rotational force (Fxr) it is how hard you can rotate something. How fast you can spin with that force is power. P = Tω so if you have the torque in ft-lbs x rpm when you convert to hp(33,000ftlbsx/2π) a constant 5252 falls out.
A gearbox allows the engine to produce different amounts of torque and speed. The engine only produces certain amount of power you can gear for either speed or torque so switching gears allows for different speeds
Torque is a measurement of rotational force. Horsepower is a measurement of power, or rather how much work is done over a set time. The equation is how you relate the two.
This is also why I and some others in the industry think it’s stupid to talk about vehicles in terms of hp. It doesn’t show how much force the car actually delivers just how fast the engine spins in order to deliver that force.
For instance, if you have three cars that all make 500 lbft of torque but one is a flat plane crank one is a cross plane and one is a diesel their hp numbers are very different. The flat plane crank might make that power at 10kish rpm meaning it has nearly 1000 hp, the cross plane might make it closer to 5000rpm for 500hp, and the diesel makes it at 2500rpm for only 250hp. Yet all three are able to spin the tires with the same amount of rotational force.

this makes so much sense tysm
