How Does the Center of Gravity Influence an Object's Stability in Static Equilibrium?

The center of gravity (CG) is super important for keeping things steady when they’re not moving. Here’s how it works:

  1. Where is It?: The CG is like the balancing point of an object. It’s where we think all the weight is located. If this point is low, like in a sports car, the car is less likely to tip over because it has a wider base. But if the CG is high, like in a tall building, it can be easier for the building to fall over during strong winds or earthquakes.

  2. Staying Steady: An object stays stable when its CG is right above its base of support. Think about when a person stands on one leg. Their CG changes and they might lose balance. If the CG goes outside their base of support—like leaning too far—they will fall over.

  3. A Simple Formula: We can think about CG and balance like this:

    Moment about the tipping edge=W×d\text{Moment about the tipping edge} = W \times d

    Here, WW is the weight and dd is the distance from the CG to the edge of the support base.

So, keeping the CG low and centered helps things stay balanced, whether it’s furniture or cars. I’ve seen this principle work not only in engineering but in everyday objects too!
