Understanding Internal Forces

What happens to a spring when it is compressed and then released?

• It breaks into pieces.

• It exerts a force in the opposite direction and returns to its original shape.

• It exerts a force in the same direction.

• It remains compressed.

Which force is created when an object is stretched or elongated?

• Compression

• Tension

• Torsion

• Bending

On a beam bridge, where is compression typically found?

• In the middle

• On the upper surface

• At the ends

• On the lower surface

What type of force is created when an object is twisted?

• Torsion

• Bending

• Tension

• Compression

When bending an object, which side develops tension?

• The side that is compressed

• The side that is elongated

• Both sides

• Neither side
