Question

which type of hammer uses a cavity filled with lead or sand to reduce bounce back?
a) ball - peen
b) rubber mallet
c) dead - blow
d) small sledgehammer

Explanation:

A dead - blow hammer has a cavity filled with lead or sand. When it strikes an object, the lead or sand absorbs the energy that would otherwise cause bounce - back. A ball - peen hammer is mainly used for shaping metal (e.g., peening rivet heads). A rubber mallet uses rubber to dampen impact but not a cavity with lead or sand. A small sledgehammer is a heavy - duty hammer for tasks like driving stakes and does not have this cavity - filled design for reducing bounce - back.

Answer:

C. Dead - blow
