Quick Return Mechanism Slider Crank Coupler -Stroke Follower Ground- Pivot Ground Link = 3 1/4 inch Crank Link 1 1/8 inch Follower 7 inch Pivot to Slider Path = 4 3/4 inch 1) The Quick Return Mechanism shown is a Crank Shaper. Using the given link lengths, draw a full scale schematic diagram and graphically determine by exact measurement: A) Length of the Stroke (inches) B) Forward Angle, α (degrees) C) Return Angle, ẞ (degrees) D) Time Ratio, TR = α/ẞ 2) Calculate the Length of the Stroke (inches), α (degrees) and B (degrees) using Geometry and by observing the Similar Right Triangles. 4 3/4
