match one of the 5 stresses with their example.
tension choose
compression choose turbine shaft : tension and compression when object is twisted
wing during flight / lift : tension and compression due to flexing
deflecting beam torque wrench : a distortion force where an object is forced out of shape
rivet : crushing
pulley : pulling object apart
clevis bolt : trying to cut or slice an object
torsion choose
bending choose
shear choose
strain choose
question 3

Explanation:

To solve this, we analyze each stress type:

• Tension: Involves pulling an object apart. The option "pulley / pulling object apart" matches.
• Compression: Involves crushing or pushing together. "rivet : crushing" matches.
• Torsion: Involves twisting. "turbine shaft : tension and compression when object is twisted" (focus on twisting) matches.
• Bending: Involves flexing (causing tension/compression due to bending). "wing during flight / lift : tension and compression due to flexing" matches.
• Shear: Involves slicing/cutting forces. "clevis bolt : trying to cut or slice an object" matches.
• Strain: Involves distortion (force out of shape). "deflecting beam torque wrench : a distortion force where an object is forced out of shape" matches.

Answer:

• Tension: pulley / pulling object apart
• Compression: rivet : crushing
• Torsion: turbine shaft : tension and compression when object is twisted
• Bending: wing during flight / lift : tension and compression due to flexing
• Shear: clevis bolt : trying to cut or slice an object
• Strain: deflecting beam torque wrench : a distortion force where an object is forced out of shape
