Abstract

This paper addressed the relationship between linear velocity of a scotch yoke mechanism during motion. Understudying the working principle of the scotch yoke mechanism as regards to how it converts circular motion into linear motion. Experimental apparatus were set up which involves calibrating of the motor speed, calibrating of the motor speed, calibrating the timing of the circuit from theoretical knowledge which led to the scotch yoke mechanism model construction. Mono–stable multi–vibrator and DC motor speed controller circuits were introduced into the design. Linear velocity produced independently by Tachometer and Timer circuit experiment was determined. There is close relationship between the angular speed and linear velocity produced from the Tachometer experiment and the timer circuit experiment, which helps to have a model for demonstrating the motion conversion characteristics of the scotch yoke mechanism. These findings demonstrated the motion characteristics of the scotch yoke mechanism; also the model will be useful in teaching and research purposes.
