I also asked the same question but could not find satisfactory answer, so I decided to try smacking this myself. Note that this discussion is limited to petrol engines. This may be a bit long but here it goes.
It's a bit theoretical but it is important to know "the basics" prior to further discussion. "Torque" is actually the amount of "work" done (in Newton.meter or Joule). It is a function of how much Newton of "force" being exerted on the engine's piston during expansion in "combustion stroke". If you refer to Otto / Diesel Cycle Temperature-Entropy (T-s) diagram, engine output can be increased at higher pressure ratio (volumetric energy from air density) or higher firing temperature (thermal energy by adding more fuel). So, more air + more fuel = more power..
What is power then? Well I simply view "power" as the "rate of doing work" (Joule/sec or kW). Hence, for the same amount of torque, the power increases at higher RPM (Power = Torque X Rotational Speed). Agree?
OK, now let's discuss on the power / torque vs RPM curve usually supplied by car manufacturers. In naturally-aspirated (NA) engines, initially the torque slowly increase, peaks at certain speed (say 4000 RPM) and started to decline beyond that point. As we've understand that torque and power are related, this torque dip reduces the power increase slope and eventually diminishes the power at a later speed (say 6500 RPM). This happens when the depleting of torque is more significant than increase in engine speed. Make sense, right?
In NA engines, I think the torque started to reduce because of 2 main reasons. Firstly, limitation is on the "intake valve lift" that controls the openings of air passage into the cylinder. At higher RPM, more air is required but the flow is "choked" by this constant opening area. This is the reason why some engines are designed with "variable intake valve lift" to cater for various RPM ranges i.e. small openings at low RPM (for fuel efficiency) and larger openings at higher RPMs (to sustain or even increase torque and power).
Secondly, the air into the cylinder is always at ambient pressure regardless of engine RPM. The amount of air drawn into the cylinder solely depends on the negative "suction" created by the downward movement of the piston during intake stroke. At higher RPM, constant atmospheric inlet pressure could not catch up with rapid cylinder volume expansion from faster piston movement. This results in lower air density available for combustion (although can be compensated with higher fuel consumption).
This is where forced-induction engines come into the picture. In turbocharged or supercharged engines, air pressure at the intake is compressed to slightly above atmospheric pressure, meaning there is a "pushing" of air into the cylinder to complement the "pulling" by the piston during intake stroke. This extra help enables peak torque to be achieved much earlier (say 1500 RPM). Another benefit is sufficient amount of presurized air can be supplied at a wide span of engine speed (say 1500 to 5000 RPM) and constant torque value can be achieved within this range. This flat torque profile is what you referred as "torque plateau". Using this technique, the power output rate can be rapidly increased across the RPM and "higher peak power" can be achieved with a relatively small engine capacity. all this just by playing with the torque value!

The magnitude of the torque depends on the force applied to the beam and the distance from the point where the beam is bolted. The torque can be calculated using the formula Torque = Force x Distance.
Torque in an induction motor is proportional to slip, which is the difference between the synchronous speed and the actual rotor speed. As slip increases, torque also increases, up to a certain point. This relationship is key to understanding the motor's operating characteristics.
The maximum torque that can be applied to a beam before it reaches its breaking point is the point at which the beam can no longer withstand any additional twisting force. This is known as the breaking torque.
It is necessary to mention a reference point when defining torque because torque is a measure of the rotational force around an axis. The reference point helps specify the direction in which the force is applied and provides a point of comparison for the rotational effects of different forces. Without a reference point, it would be unclear which direction the torque is acting in and how it is affecting the object.
The magnitude of the torque about a pivot point is given by the product of the force applied and the distance from the pivot point to the line of action of the force, multiplied by the sine of the angle between the force and the lever arm. Mathematically, torque = force * distance * sin(angle).
The Grand Canyon is a "gorge" or "canyon" if you wish. Hence the name Grand Canyon. However, there are two "plateau's" on either side of the canyon which could be considered part of the GC, from a certain point of view.
The freezing point of a pure solvent is a plateau. As the solvent cools, its temperature decreases until it reaches its freezing point, at which point the temperature remains constant until all of the solvent is frozen.

I believe that is the maximum horsepower and torque and at what RPM they occur

The highest plateau in Asia is The Tibetan Plateau. Believe it or not, it is the highest plateau in the world.
The seizure and control of the Motoyama Plateau marked the turning point .
A plateau is a flat-topped elevated landform that rises sharply from its surroundings. It is typically characterized by steep cliffs on one or more sides and can be formed by the uplift of the Earth's crust or by erosion. An example of a plateau is the Colorado Plateau in the southwestern United States, which is known for its colorful canyons and rock formations.

Max torque and breakdown toarque are the same...,.the point at which a motor will stop/stall.
