Question 1: The crank OA of a mechanism as shown in figure below rotates uniformly at 120 rpm counter-clockwise. Various links have following dimensions: OA = 200 mm, AB =

1500 mm, BC = 600 mm,CD = 500 mm Point E (Joint) is located on link CB (EB = 400 mm) as per figure. а)Identify total number of links and full joints in the mechanism. Can we declare this complex mechanism as planar mechanism? b)Make appropriate scale and employ related engineering knowledge to draw the current position and velocity diagrams for the mechanism Finally interpret the diagrams and use related formulae to estimate linear velocity (mm/sec) of slider,and angular velocity (rad/sec) for link CD and normal acceleration of Point C (Note: No need to draw c)Acceleration diagram)
