Problem 1: A metering pump was design such that a movable pivot controls the stroke of the crank.The pivot is adjustable to any position through a 90 arc about the center of the crank.When the crankshaft-to-movable-pivot line is perpendicular to the crosshead motion,the stroke is maximum.When it is in line with the crosshead motion,the stroke is minimum.Draw the unscaled kinematic diagram of this linkage.Determine the D.O.F of this linkage -Maximum Stroke Crosshead 3 Slide Block Connecting Rod Yoke Displacement to Change from Maximum to Minimum Stroke Movable Pivot Maximum Stroke Position Minimum Stroke Moving Pivot Minimum Stroke Position Solution: 11 ME 337 homework –lecture2 Due in class on Sept. 25, 2014 Course ID: Name: Please use A4 size paper and staple them together. Problem 1: A metering pump was design such that a movable pivot controls the stroke of the crank. The pivot is adjustable to any position through a 90° arc about the center of the crank. When the crankshaft-to-movable-pivot line is perpendicular to the crosshead motion, the stroke is maximum. When it is in line with the crosshead motion, the stroke is minimum. Draw the unscaled kinematic diagram of this linkage. Determine the D.O.F of this linkage. Solution:
