How Manual Transmission works - automotive technician shifting

The video tutorial explains the components of a vehicle's drivetrain, including the engine, clutch, transmission, and differentials. It compares manual and automatic transmissions, emphasizing the role of gear ratios in controlling speed and torque. The concept of torque is illustrated using wrenches, and the function of gear trains is explained. The video also details the components of a transmission system, such as shafts and synchronizers, and describes the gear shifting process. Finally, it provides formulas for calculating gear ratios and torque in simple and compound gear trains.

What is the primary function of the clutch in a vehicle's drivetrain?

• To engage or disengage the engine's power to the transmission

• To increase the vehicle's speed

• To provide power to the wheels

• To control the vehicle's steering

Why is it difficult to start pedaling a bike in a high gear?

• High gear decreases the bike's stability

• High gear increases the bike's weight

• High gear provides low speed but high torque

• High gear provides high speed but low torque

What is the effect of using a longer wrench on a seized nut?

• It decreases the torque applied

• It makes it harder to turn the nut

• It increases the torque applied

• It has no effect on the torque

What happens when the driven gear is half the diameter of the driver gear?

• The driven gear rotates slower

• The driven gear rotates faster

• The driven gear rotates at the same speed

• The driven gear does not rotate

What is the role of the idler gear in a gear train?

• To increase the speed of the output gear

• To reverse the direction of rotation

• To provide additional torque

• To reduce the size of the gear train

What is the purpose of a compound gear train?

• To provide more power to the wheels

• To take up less space while changing speed and direction

• To change the direction of rotation

• To increase the size of the gear train

What is the purpose of a synchronizer hub in a transmission system?

• To increase the vehicle's speed

• To lock the hub in place with the shaft

• To provide power to the wheels

• To change the direction of the vehicle

What happens when the clutch is engaged with the engine?

• The output shaft stops rotating

• The input and countershaft rotate

• The vehicle's direction changes

• The vehicle's speed decreases

How does a synchronizer blocker ring prevent gear grinding?

• By reducing the torque of the gear

• By increasing the speed of the gear

• By blocking the gear from changing until speeds are synchronized

• By changing the direction of the gear

How is the speed of the output gear calculated in a gear train?

• By adding the input speed to the gear ratio

• By dividing the input speed by the gear ratio

• By subtracting the gear ratio from the input speed

• By multiplying the input speed by the gear ratio
