### Transcript

• 1. Relative Acceleration Lecture Notes
• 2. The Slider-Crank Mechanism
• 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.
• 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.
• 3. Example 1:
• 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.
