Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the mechanism classification?A type of linkage mechanism for force distribution and equalization
2. What is the core engineering principle?Leverage and torque applied to achieve balanced force distribution
3. What is a whippletree?A whippletree is a simple bar that pivots near its middle. It spreads one pulling or pushing force to two or more ends. This helps keep everything balanced and safe.
4. How does a whippletree share weight?When you pull on the middle of the bar, the ends pull equally if they are the same distance away. If one end meets more resistance, the bar tilts and changes the lengths of the arms. The forces then adjust until the total pull stays the same.

Leverage: The mechanical advantage gained by means of a lever, involving a pivot point and applied forces.
Torque: A twisting or turning force that tends to cause rotation around an axis.
Stress Concentration: A location in an object where stress is significantly higher than the average stress across the object.
Kinetic Sculpture: Art that contains moving parts or depends on motion for its effect.
