Question

Final Examination. May, 31, 2019 Exam duration is 120 minutes and questions are equally weighted 1) in the figure an in-ine Sider-Crank Mechanism is shown with dimensions. Wite down the A loop mechanism. Then separate it into components and by using the component equations. calculate the position of the sider as its distance to origin when crank angle θ is 60 equation according to the vector loop shown aside. which represents the AB 5 cm, BC 10 cm Calculate the velocity of the sider of the mechanism in question by magnitude and direction if the crank is rotating ccw with a speed of 2 rad/sec. by differentiating the components of the vector loop equation. Find the same velocity by a velocity polygon and see if the results match or not. C constant velocity of 2 rad/sec in ccw direction by differentiating the components of the velocity loop equation. Then find the same acceleration by using an acceleration polygon. Do the results match ? calculate the acceleration of the slider of the mechanism in question-1 if the crank has a
