Gear and engine speed are related in that the gear ratio determines how the engine speed translates into the speed of the vehicle's wheels. In lower gears, the engine speed is higher relative to the vehicle speed, providing more power for acceleration. In higher gears, the engine speed is lower relative to the vehicle speed, allowing for more efficient cruising at higher speeds. The gear selection affects how the engine's power is utilized to propel the vehicle. **

Your engine may hum during gear changes because of the change in load and speed. When you shift gears, the engine has to adjust to the new speed and load requirements, which can cause it to hum as it works to maintain the proper RPM. Additionally, the transmission and clutch engagement during gear changes can also contribute to the humming sound. This is a normal part of the operation of a manual transmission vehicle and is not usually a cause for concern. **

Gear speed refers to the speed at which the gears in a vehicle are rotating, while engine speed refers to the speed at which the engine is running, measured in revolutions per minute (RPM). In a manual transmission vehicle, the gear speed can be different from the engine speed because the gears can be shifted to change the speed at which the wheels are turning in relation to the engine speed. In an automatic transmission vehicle, the transmission system adjusts the gear speed to match the engine speed based on the driving conditions. **

Stalling the engine in third gear is not ideal as it can put unnecessary strain on the engine and transmission. It can also potentially cause damage to the clutch system over time. Additionally, stalling in third gear can be dangerous if it happens unexpectedly while driving, as it can lead to a loss of control over the vehicle. It is best to practice smooth shifting and clutch control to avoid stalling in any gear. **
