The gear used in a bus to run the rear wheel is the differential gear.

• The differential gear allows the rear wheels of a bus to rotate at different speeds while turning.

• It is located in the rear axle housing and consists of a set of gears.

• The differential gear transfers power from the engine to the rear wheels while allowing them to rotate at different speeds.

• It helps in smooth turning and prevents tire wear.

• Examples of differential gear types used in buses include open differ...read more

Air is used in monosuspension for providing cushioning and absorbing shocks.

• Air is commonly used in monosuspension systems of vehicles to provide a smooth and comfortable ride.

• The air acts as a cushion and absorbs shocks from bumps and uneven surfaces.

• Monosuspension systems with air can be found in motorcycles, bicycles, and even some cars.

• Air pressure can be adjusted to customize the suspension for different riding conditions or preferences.

Both hardwork and smartwork are important, but a combination of both is the most effective approach.

• Hardwork is essential for building a strong work ethic and achieving long-term goals.

• Smartwork involves finding efficient ways to accomplish tasks and maximizing productivity.

• Combining hardwork with smartwork allows for optimal results by working diligently and strategically.

• For example, a student who studies hard but also uses effective study techniques like mnemonics or space...read more

CP and CPK are statistical measurements used to assess the capability of a process to produce products within specifications.

• CP is a measure of process capability that compares the spread of the process to the tolerance range.

• CPK is a measure of process capability that takes into account the centering of the process within the tolerance range.

• CPK is a more accurate measure than CP because it considers both the spread and centering of the process.

• A CPK value of 1.33 or higher ...read more
