Final answer:
A component block diagram for the manual steering system of an automobile includes the steering wheel, steering column, and steering gear. The steering wheel serves as the input, the steering column transmits the command, and the steering gear converts the motion to turn the wheels.
Step-by-step explanation:
A component block diagram for the manual steering system of an automobile can consist of three main components: the steering wheel, the steering column, and the steering gear. The steering wheel acts as the input, where the driver provides a steering command. This command is then transmitted through the steering column to the steering gear, which converts the rotational motion into linear motion to turn the wheels of the car.
Example: The driver turns the steering wheel clockwise. This rotational motion is transmitted through the steering column and reaches the steering gear. The steering gear converts the rotational motion into linear motion and moves the wheels of the car to the right.
