Week 9 - Mechanical Systems Quiz

Define torque and describe its role in mechanical systems.

• A measure of rotational force; it causes an object to rotate around an axis.

• A type of linear force; it applies pressure in a straight line.

• A measure of electrical energy used in motors.

Why is maintaining constant velocity important in couplings?

• It reduces vibrations and ensures smooth power transmission.

• It increases the rotational speed of shafts.

• It enhances the visual appeal of mechanical designs.

List three examples of systems where velocity ratios are critical.

• Solar panels, air conditioners, and telecommunication systems.

• Automotive drive shafts, robotic arms, and CNC machines.

• Hydraulic lifts, electrical circuits, and water pumps.

What happens when velocity ratios are not maintained in a coupling system?

• The system continues functioning without any issues.

• The system experiences wear, vibrations, and loss of efficiency.

• The system doubles its efficiency due to misalignment.

Which type of coupling is typically used to correct misalignment in shafts?

• Universal joint coupling.

• Magnetic coupling.

• Threaded coupling.
