L2 Chassis - Bearings Lesson

Multiple Choice

Why are bearings considered essential components in machinery and mechanical systems?

• They reduce friction and support loads, allowing for efficient motion.

• They increase friction to slow down machinery.

• They are used only for decorative purposes.

• They are only used in electrical systems.

Multiple Choice

Which of the following best describes the direction of axial movement in mechanical systems?

• Along the axis of a component or system

• Perpendicular to the axis of a component or system

• In a circular path around the axis

• Randomly within the component

Fill in the Blanks

Ball bearings are designed to support both

and axial loads.

Multiple Select

Which of the following are advantages of ball bearings?

• Low friction

• Durability

• Versatility

• Require frequent lubrication

Multiple Choice

Cylindrical roller bearings are best suited for handling which types of loads?

• High radial loads and moderate axial loads

• Low radial loads and high axial loads

• Only axial loads

• Only radial loads

Multiple Choice

Which type of roller bearing is designed to handle both radial and axial loads and is commonly used in wheel hubs?

• Tapered Roller Bearing

• Needle Roller Bearing

• Spherical Roller Bearing

• Ball Bearing

Multiple Select

Which of the following are advantages of roller bearings over ball bearings?

• Higher load capacity

• Greater durability

• Lower cost

• Larger contact area

What are the main structural components of a thrust bearing and how do they contribute to its function?

Fill in the Blanks

A thrust bearing is designed to handle

loads, which are forces applied parallel to the shaft.

Multiple Choice

Which type of thrust bearing is ideal for higher load capacities?

• Ball Thrust Bearing

• Roller Thrust Bearing

• Needle Thrust Bearing

• Magnetic Thrust Bearing

Multiple Choice

Which of the following is NOT an advantage of thrust bearings?

• They minimize friction and wear

• They are made from high-strength materials

• They are designed to withstand significant axial loads

• They are generally less expensive than rolling-element bearings

Open Ended

Explain how the structure of plain bearings contributes to their function in supporting loads and enabling motion.

Multiple Select

Which of the following are types of plain bearings?

• Journal Bearings

• Thrust Bearings

• Linear Bearings

• Ball Bearings

Fill in the Blanks

Plain bearings often require regular

to maintain performance and prevent wear.
