Question

1. which part is used to move mechanical power directly from the motor to a wheel (without using any gears)?

a. wheel
b. motor
c. spacer
d. 3 - hole bearing
e. gear or sprocket
f. axle

Explanation:

To determine the part that transfers mechanical power directly from the motor to a wheel without gears, we analyze each option:

• Option A (wheel): The wheel is the component being powered, not the one transferring power to it.
• Option B (motor): The motor generates power, not transfer it directly to the wheel without gears (and the question is about the part doing the transfer, not the power source).
• Option C (spacer): A spacer is for spacing, not power transfer.
• Option D (3 - hole bearing): A bearing reduces friction, not transfer power.
• Option E (gear or sprocket): The question specifies "without using any gears", so this is excluded.
• Option F (axle): An axle can connect the motor (or its output) directly to the wheel, transferring mechanical power without gears by acting as a shaft to transmit torque and rotation.

Answer:

F. axle
