medium Q7 of 15
Step-by-Step Solution
Step 1: Identify the simple machine in a nutcracker
A nutcracker works as a lever, where a small effort applied at a longer distance from the fulcrum produces a large force to crack the nut.Step 2: Analyze other options
Pulley changes force direction, screw converts rotational to linear force, wedge splits objects; none fit nutcracker function.Final Answer:
Lever → Option BQuick Check:
Nutcracker mechanism = Lever ✅
Quick Trick: Nutcracker = lever increasing applied force.
Common Mistakes:
MISTAKES- Confusing nutcracker with wedge or screw due to shape.
