12 Questions
What is the main difference between center of gravity (CG) and centroid?
Center of gravity focuses on equilibrium and stability, while centroid is about finding the center of mass or area of a shape.
Which point is considered the center of gravity for an object?
The point where the gravitational force can be concentrated
In what context do engineers mainly use the centroid?
To design structures and calculate moments of inertia
Why is understanding the location of the center of gravity crucial in designing vehicles?
To ensure stability and prevent tipping
What does the centroid represent for a two-dimensional area?
The geometric center or average position of all points in that area
How do engineers apply the concept of center of gravity in designing structures?
To ensure stability and prevent tipping
What is the key difference between the center of gravity (CG) and the centroid?
The center of gravity considers material properties, while the centroid does not.
Which property quantifies an object's resistance to torsional deformation?
Polar moment of inertia
What does the radius of gyration represent?
The distribution of mass around a central axis
How is the centroid calculated for a two-dimensional shape?
By finding the average of x and y coordinates
What influences both the shape and material properties in determining the center of gravity?
Both material properties and shape
What does the polar moment of inertia measure with respect to a central axis?
Twisting deformation resistance
