• For example, in manufacturing, a Pareto chart can show the most common defects affecting product quality.

The center of gravity of a vehicle shifts towards the outside of the turn, causing a lateral force.

• The lateral force causes the vehicle to lean towards the inside of the turn.

• The speed of the turn and the height of the center of gravity affect the amount of lateral force.

• If the center of gravity is too high, the vehicle may tip over.

• Anti-roll bars and suspension systems can help reduce the lateral force and improve stability.

Use Math.random() function to generate random number between 1-6.

• Use Math.random() function to generate a random decimal number between 0 and 1.

• Multiply the random decimal number by 6 to get a random decimal number between 0 and 6.

• Use Math.floor() function to round down the decimal number to the nearest integer.

Triangular structure is more stable due to its inherent strength and ability to distribute weight evenly.

• Triangular structures distribute weight evenly, reducing stress on individual components.

• They are inherently strong due to their shape, which allows for better load-bearing capacity.

• Examples include the Eiffel Tower and suspension bridges.

• Rectangular structures are less stable as they are more prone to buckling and bending under stress.

The current in a DC-DC converter is converted from one voltage level to another while maintaining power conservation.

• The current in a DC-DC converter is typically stepped up or stepped down to achieve the desired output voltage.

• The conversion process involves switching elements like transistors to control the flow of current and voltage.

• Efficiency of the converter is crucial to minimize power losses during the conversion process.

• Examples of DC-DC converters include buck conve...read more
