OBJECTIVE:
To gain in-depth practical knowledge and to improve the Understanding of the mechanism
RESOURCES REQUIRED:
1)Model of scotch yoke
2)class notes
3)Text book
4)Ruler
5)Vernier calipers
THEORY:
Scotch yoke is a mechanism used to convert rotary motion into Sliding motion. This mechanism is obtained from an inversion of the double Slider crank chain.
Description of the model:
A model of scotch yoke mechanism is to be used for study. A diagram of the Model is shown in fig .4. the model consist of a slider plate guides G1 and G2 Mounted on the base plate of the model. The slider plate carries a slot AB in Which a slider block ‘Q’ as centre, and drives the slider block Q. arm OR. the Arm OR is free to rotate about point ‘O’ as centre, and drives the slider block ‘Q’. The position of point ‘R’ can be changed by selecting one of the four holes Provided on the arm OR and shifting the screw to the particular hole. The
Crank OR is further rigidly linked to a handle which is used to provide manual Rotation to the link, and thereby impart motion to the mechanism. An extension To the rotating arm OR is provided which carries a pencil to trace the movement Of the arm.
