Wear heavy-duty gloves Use a punch holder Ensure the work area is well-lit Wear eye and face protection

12. What is the condition called when the end of a punch deforms into the shape shown in Figure 9-7 (B) after continuous use?

Crowning Mushrooming Splitting Chipping

13. What is the primary purpose of a prick punch as shown in Figure 9-9?

To drive rivets out of holes To break apart hardened materials To make reference points on metal for drilling To create a decorative pattern on a surface

14. Why should a prick punch NEVER be used to drive a pin or rivet?

It is too heavy for the task. It can cause the metal to overheat. Its point is delicate and can be easily damaged. It is not long enough to push the pin through.

15. Under what circumstance is a punch holder (Figure 9-8) specifically recommended for use?

When making a very light mark When a hard blow is required When working with plastic materials When the punch is brand new

16. What is the primary advantage of using a punch compared to a direct hammer blow?

It makes less noise. It is faster. It concentrates the force in a small area, increasing pressure. It absorbs the shock to protect the work surface.

17. According to the caption for Figure 9-6, how has the usage of mallets changed?

Rawhide mallets are now more common than plastic mallets. Both mallets are now considered obsolete. Plastic mallets have virtually replaced rawhide mallets for most uses. Rawhide and plastic mallets are now made from the same material.

18. What is the correct procedure for fixing a punch that has become mushroomed?

Hammer the end flat again. Heat the end and reshape it. Discard the punch as it is no longer usable. Remove the mushroom shape and restore the crown using a bench grinder.

19. Which illustration in Figure 9-7 shows the safe, correct shape for the end of a punch?

A B Both A and B are correct Neither A nor B is correct

20. According to Figure 9-2, what distinguishes a cross peen hammer from a straight peen hammer?

The weight of the head The length of the handle The orientation of the wedge-shaped peen relative to the handle The material of the striking face

21. How are sledge hammers sized?

By the overall length of the tool By the diameter of the flat faces By the total weight including the handle By the weight of the head without the handle

22. What is the primary purpose of a claw hammer with a curved set of claws, as described in Figure 9-3?

Splitting wood Pulling nails Shaping metal Driving stakes

23. Body hammers, also known as planishing hammers, are specifically designed for which task?

26. In addition to pulling nails, what is a specific use for a claw hammer with a straight set of claws?

Stretching metal Riveting Splitting wood Smoothing surfaces

27. What material were early soft-faced mallets, used in aviation, commonly made from?

Heavy with small, hard faces Lightweight with large, smooth faces Made of soft rubber or rawhide Having one flat face and one claw

29. What is a notable limitation mentioned about the use of sledge hammers in Figure 9-4?

They are only for woodwork They are rarely used in aviation maintenance They cannot be used on metal They are too light for heavy jobs

30. According to the text, what is the first safety precaution you should take before using any hammer or mallet?

31. What is the ball end of a ball peen hammer typically used for in commercial sheet metal work?

A) Driving nails B) Straightening rolled edges C) Peening over rivets D) Pulling out nails

32. Why should a claw hammer not be used on hardened steel parts?

A) The handle is too fragile for heavy impact. B) The head is typically hardened, making it brittle and susceptible to chipping. C) The crowned face will slip off the steel. D) The claws can get in the way.

33. What is the primary purpose of the wedge-type end on a cross peen or straight peen hammer?

A) To drive nails with precision. B) To peen rivets in aircraft work. C) To crease metal for a bend or straighten a rolled edge. D) To break hardened materials.
