Scissors are like a double-lever system. Which of the simple machines in Figure 9.23 and Figure 9.24 is most analogous to scissors?
Step 1 of 1:
The lever systems make our job easier. They are used to handle heavier objects easily. The scissors are double lever systems. The location of the fulcrum is located at the center of the scissors. That is where the hinge is located. We can identify the given lever system (a nail puller, a wheelbarrow, and a shovel) that matches the scissor. The shovel is analogous to the scissors. Both have the shorter lever arm. The fulcrum of these two simple machines is closer to point where the input force is applied.
