• ## Blueberries Case Study

blueberries change its properties after some time. So, the device will use their properties as its working methodology. Then it will select fresh blueberries on the basis of their properties. Theory: As blueberries age or become bruised, they tend to soften. Therefore, their coefficient of restitution decreases. First we need to understand what is coefficient of restitution. Coefficient of Restitution: COR is the extent of restitution of an impact between two objects. Also, for the kinetic energy how long it remains for the objects to bounce from each other. COR = e = (Relative velocity after collision)/(Relative velocity before collision) Range of Coefficient of Restitution: For COR range, it’s between 0 and 1.0. e = 0: Perfectly inelastic. The items don 't move separated after the impact. 0 < e < 1: Inelastic. Kinetic energy disappears. e = 1: Perfectly elastic. Kinetic energy remains. e < 0: When velocity of share equal directions. e > 1: When energy is free. Mathematical Expressions: Coefficient of restitution: e = (Vb-Va)/(Ub-Ua) Object’s velocity after impact: e = V/U Design: The form of design is shown in the figure below. Explanation: Here, blueberries are dropped from a height of 5 ft on an inclined plane. If the blueberry is fresh one, it will bounce back with huge force and will go above the hurdle of height “h” direct into a collecting bucket. If the blueberry is bruised or aged,…
