Unformatted text preview: 162A. Introduction to Mechanisms and Mechanical Systems Chapter 4: Acceleration Why is acceleration important? s Acceleration analysis involves determining the manner in which certain points of a mechanism are either “speeding up” or “slowing down” s Acceleration, therefore, determines the time taken to move from point A to point B s Acceleration determines inertial forces, which in turn requires that links and joints are strong enough to withstand these (and other applied) forces s Just as we looked at linear and angular velocities, we’ll study linear and angular acceleration Topics s Definition of Acceleration s Angular Acceleration elative Acceleration (or Acceleration s Relative Acceleration (or Acceleration Difference) between Points of a Rigid Body s Complex Algebra Method for Acceleration Analysis Definition: Acceleration s A point at location P has velocity V P s Δ T later, it has moved to P’ where it may have a different velocity V P ’ s Δ V P = V P ’ – V P s Average acceleration during time Δ T is Δ V P / Δ T s A P = ( Δ V P / Δ T) = d V P /dt = Definition: Acceleration (contd.)Definition: Acceleration (contd....
