Match the definitions to the most appropriate mechanism. Column A 1. __ converts rotary motion (circular gear) to linear motion 2. __ turns rotary motion into linear motion and significantly increases the output force 3. __ converts rotary motion into reciprocating motion. Column B a. Rack and Pinion b. Crank and Slider c. Lead Screw

## Step 1<br />The first definition describes a mechanism that converts rotary motion (circular gear) to linear motion. This is the function of a Rack and Pinion mechanism. In this mechanism, the circular gear (pinion) is connected to a linear gear (rack), which allows the circular motion to be converted into linear motion.<br /><br />## Step 2<br />The second definition describes a mechanism that turns rotary motion into linear motion and significantly increases the output force. This is the function of a Lead Screw mechanism. In this mechanism, the rotary motion is converted into linear motion through the rotation of a screw, which also increases the output force.<br /><br />## Step 3<br />The third definition describes a mechanism that converts rotary motion into reciprocating motion. This is the function of a Crank and Slider mechanism. In this mechanism, the rotary motion is converted into reciprocating motion through the rotation of a crank, which moves the slider back and forth.
