Vehicle and Structure Stability Concepts

The video explores the concept of center of gravity and its impact on the stability of structures. A low center of gravity enhances stability, as seen in pyramids and trees, while a high center of gravity can lead to instability, exemplified by the Leaning Tower of Pisa. Shifting the center of gravity, such as in sailboats, can improve stability. The video also discusses the importance of center of gravity in vehicles and architecture, highlighting its role in preventing rollovers and enhancing earthquake resistance. Understanding center of gravity is crucial for designing stable and reliable structures.

What is a critical factor in determining the stability of structures?

• Height of the structure

• Location of the center of gravity

• Color of the structure

• Material used

Why is a low center of gravity important for stability?

• It makes the structure more colorful

• It increases the weight of the structure

• It helps in even weight distribution

• It makes the structure taller

What is the balance point within an object where all its weight is evenly distributed?

• Center of buoyancy

• Empire State Building

• Leaning Tower of Pisa

• Burj Khalifa

How do sailors prevent a sailboat from capsizing?

• By increasing the sail size

• By adding more weight to the top

• By using a keel to lower the center of gravity

• By shortening the mast

Why should vehicles have a low center of gravity?
