A rotary potentiometer is designed to measure rotational movement, providing a variable resistance output based on the position of a rotating shaft. On the other hand, a linear potentiometer measures linear movement, offering a variable resistance output based on the linear position of the sliding wiper along a straight track.
Linear motion can be converted to rotary motion using mechanisms like gears, pulleys, or cams. For example, a rotating gear can engage with another gear to convert linear motion into rotary motion. This conversion allows for transferring power from one direction to another efficiently.
Cam and follower mechanism: Converts rotary motion into linear motion by translating the motion of a cam into the linear motion of a follower. Rack and pinion system: Uses a rotating gear (pinion) to move a linear rack back and forth, converting the rotary motion into linear motion. Scotch yoke mechanism: Utilizes a circular motion to drive a sliding block in a straight line, converting rotary motion to linear motion. Lead screw mechanism: A rotating screw that moves a nut along its threads, translating rotational motion into linear motion.
The biomechanical principle that creates linear and rotary motion is the application of muscular forces to bones via tendons. When muscles contract and pull on bones, they generate linear motion along the axis of the muscle contraction. Additionally, the orientation of the muscles around joints can also produce rotary motion when the muscles contract asymmetrically.
The main types of movement for mechanisms are rotary, linear, reciprocating, and oscillating. Rotary movement involves rotating around an axis, linear movement involves moving in a straight line, reciprocating movement involves back-and-forth motion, and oscillating movement involves swinging or vibrating in a regular repeating pattern.
The four types of motion mechanisms are rotary motion, linear motion, oscillating motion, and reciprocating motion. Rotary motion involves circular movement, linear motion involves movement in a straight line, oscillating motion involves back and forth movement, and reciprocating motion involves alternating movement in opposite directions.
