Answer :
Final answer:
The crowbar is the claw hammer that would make it easier to get the nail out of the wood with the same force. Lever principles, mechanical advantage, and force application in levers contribute to easier nail removal. The correct option is C .
Explanation:
The crowbar (option c) is the claw hammer that would make it easier to get the nail out of the wood if the same force was applied in the same direction. This is due to the leverage principle inherent in the design of the crowbar, allowing for easier removal of the nail.
- A lever system like a crowbar incorporates the principles of mechanical advantage, where the force applied at a greater distance from the pivot point exerts a greater force on the nail, making removal easier.
- By applying the same force in the same direction but with a longer distance from the pivot point, the crowbar can exert a more significant force on the nail, increasing the effectiveness of nail removal.
- Understanding the mechanics of levers and how they amplify force through a longer arm allows for efficient use of tools like the crowbar in various applications, including nail removal.
