Q3. Why does the torque value after a certain rpm flattens ?
Ans. 
Torque flattens after a certain RPM due to engine limitations and efficiency factors.
• At higher RPMs, engine components experience increased friction and heat, leading to reduced torque output.

• Engine design, intake/exhaust flow, and fuel delivery systems can also limit torque output at higher RPMs.

• Peak torque is typically achieved at a specific RPM range, beyond which the torque curve flattens out.

• Efficiency considerati...read more

Q4. Why does the power keeps rising even if the torque flattens out ?
Ans. 
Power keeps rising even if torque flattens out due to the relationship between the two variables.
• Power is the rate at which work is done or energy is transferred, calculated as the product of torque and angular velocity.

• Even if torque flattens out, the power can continue to rise if the angular velocity increases.

• This is because power is a function of both torque and angular velocity, so an increase in one can compensat

Q5. What is traction control, and and end and it's difference ?
Ans. 
Traction control is a system that helps prevent wheel spin during acceleration, while an end is the point where a vehicle's acceleration is limited due to loss of traction.
• Traction control helps maintain traction by reducing engine power or applying brakes to individual wheels

• An end occurs when traction control is unable to prevent wheel spin, causing acceleration to be limited

• Traction control is commonly found in mode...read more
