1. In a block and tackle, what is the trade-off for gaining mechanical advantage? → You must pull more rope length
2. What material property makes steel well-suited for manufacturing springs? → High elastic limit and ability to return to its original shape
3. A pyramid stands on its wide base. Why is it very stable? → Low center of gravity and wide base
4. A worm gear arrangement is known for providing: → High speed reduction
5. A metal spoon and a wooden spoon are left in the same hot soup. Why does the metal spoon feel hotter to the touch sooner? → Metal conducts heat faster than wood
6. A movable pulley system reduces the lifting force to one-third. How many rope segments support the load? → 3
7. Which material would make the best insulator to keep a house warm? → Fiberglass batting
8. If a wrench handle is made longer, turning a tight bolt becomes: → Easier
9. What happens to the force needed as you move the fulcrum closer to the load on a lever? → Less force is needed
10. If a force of 30 Newtons is applied to a box, but the box does not move, what is the force of static friction? → Exactly 30 Newtons.
11. Why does a feather fall slower than a rock in normal air? → Air resistance affects the feather more
12. An echo is produced when sound waves: → Reflect off a surface
13. What is the purpose of a switch in a circuit? → To open or close the current path
14. A pair of tweezers used to grip a small object is which lever class? → Third-class lever
15. Which arrangement lifts a heavy load with the least effort? → A multi-pulley block and tackle
16. A bottle cap is hard to twist by hand but easy with a gripper that has a wide handle because the gripper: → Increases the lever arm and torque
17. A door is hardest to open when you push: → Near the hinges
18. Pressure in a fluid is defined as: → Force divided by area
19. An inclined ramp is used instead of lifting straight up. The ramp: → Reduces the force needed over a longer distance
20. Pushing a revolving door at the edge rather than near the center is easier because the edge gives: → A longer lever arm
21. Which type of friction acts on a stationary object that is being pushed but has not yet moved? → Static friction
22. A truss is made of triangles because triangles are? → Rigid and do not deform under load
23. A 100 N block slides on a surface with a coefficient of kinetic friction of 0.3. What is the friction force? → 30 N
24. Which gear type has teeth cut at an angle, allowing quieter and smoother operation than straight-cut gears? → Helical gears
25. A weight hangs from two ropes forming a wide V. Compared to ropes hanging nearly vertical, the wide-V ropes carry? → More tension
26. When a valve spring in an engine is compressed by the camshaft, what form of energy is stored in the spring? → Elastic potential energy
27. In a first-class lever, where is the fulcrum located? → Between the effort and the load
28. Two identical pots of water are heated, one covered with a lid. Which boils faster? → The covered pot
29. In a V-belt drive, the V shape primarily helps to: → Increase grip and reduce slipping
30. If two gears must turn in the SAME direction without changing the ratio, you should add: → One idler gear
