Front

The centroid of a symmetrical object is: Located at the highest point of the object. Determined by its mass. Located on its line of symmetry. Always in the geometric center.

Back

Located on its line of symmetry.

Front

What is the mathematical property of a cross section that indicates resistance to deformation?

Back

Moment of Inertia

Front

How does the orientation of a beam affect its resistance to deformation?

Back

Beams oriented with their width perpendicular to the load resist deformation better.

Front

What does the moment of inertia of a beam depend on?

Back

The cross-sectional area’s shape and orientation

Front

Composite materials are often used in aerospace applications because:

Back

They provide both high strength and lightweight properties.
