Question

read the text.
when engineers think about the forces that can affect an object, they often consider compression, tension, torsion, and shear. to imagine these forces, think of pushing, pulling, twisting, or sliding apart the top and bottom of a cube. if you push down on the cube, you compress it. meanwhile, grabbing its ends and pulling in opposite directions creates tension. torsion is when you hold the top and bottom of the cube and twist. finally, think of shear as trying to cut or tear the cube apart—like trying to slide the top and bottom of the cube past each other in opposite directions.
which term matches the picture?
image of hands twisting a cloth
options: shear, tension, torsion, compression

Explanation:

To solve this, we analyze the forces described:

• Shear: Involves sliding parts past each other (not matching the twisting action here).
• Tension: Involves pulling in opposite directions (not twisting).
• Torsion: Defined as twisting (the image shows hands twisting a cloth, matching torsion's description).
• Compression: Involves pushing (not twisting).

The action in the image is twisting, which aligns with the definition of torsion.

Answer:

torsion
