What is tension force?

• A type of force that squeezes or pushes an object.

• A type of twisting force.

• A type of pulling force transmitted through a string, rope, or cable.

• A force that acts parallel to the surface of an object.

What is compression force?

• A type of force that pulls an object.

• A type of force that squeezes or pushes an object or material.

• A type of twisting force.

• A force that causes an object to slide.

What is torsion force?

• A type of force that pulls an object.

• A type of force that squeezes an object.

• A type of twisting force that causes an object to rotate or twist around its axis.

• A force that acts parallel to the surface of an object.

What is shear force?

• A type of force that pulls an object.

• A type of force that squeezes an object.

• A force that acts parallel to or along the surface of an object, causing it to slide or shift.

• A type of twisting force.
