Grаphicаlly design а mechanism tо take the link belоw back and fоrth between position A1B1 and position A2B2. A and B must be the coupler's pin joints (hinges). The final mechanism's input link should be actuated by a motor continuously rotating at a constant speed. The mechanism should be quick return. The time from A1B1 to A2B2 should be twice as much as the time back from A2B2 to A1B1 . Bad transmission angles are not a problem. What to submit Type below a brief explanation of the steps your process. No long essays. Type below the calculations for time ratio and their result. Paste below a snapshot picture of your mechanism, with any geometrical constructions. You can use CAD software or anything else. Makes sure to label the input link, the points A1, B1, A2, B2, fixed hinges, etc. If there are any issues (which I hope not) email me your work, a minute after the exam.
