010 relative acceleration

  1. 1. Relative Acceleration Lecture Notes
  2. 2. The Slider-Crank Mechanism <ul><li>The slider-crank mechanism probably is used in more machines than any other mechanisms. That is why special emphasis should be given to obtaining the velocities and accelerations in this mechanism. </li></ul><ul><li>Owing to the fact that most acceleration analysis for this mechanism is made when the crank is turning uniformly, it will be assumed that the crank QA is turning in a uniform angular velocity counterclockwise. </li></ul>
  3. 3. Example 1: <ul><li>A slider-crank mechanism shown has the following dimensions. QA = 4.5 inches, AB = 14 inches. Determine the instantaneous linear acceleration of A and B. Uniform linear velocity of crank QA is 4.5 ft/sec counterclockwise. </li></ul>Reference: Elements of Mechanism by V.L. Doughtie and W.H. James
