Figure 8 (c) Figure 9 illustrates a four-bar linkage mechanism that is used to operate a washing system on a vegetable harvesting line. The mechanism consists of a crank OA which moves in a limited arc and an L-shaped connecting rod AB which tilts a large bucket of water DB onto the vegetables. The crank rotates with a constant angular velocity wOA = 4x rad/s. For the instant shown with the crank vertical and the angle 8 = 30° determine...

HOMEWORK PROBLEM 1 The Grashof Criterion This problem concerns the classification of four-bar linkages. Link lengths: Lo, fixed link; Ly, driver crank; L2, coupler; L3, follower crank; L2 = 100 mm, 12 = 200 mm, 13 = 300 mm. Find the ranges of values for Lo, if the linkage can be classified as follows: a. Grashof mechanism b. Crank-rocker mechanism c. Drag link mechanism d. Double-rocker mechanism e. Change --point mechanism f. Triple-rocker mechanism

2. (20 points) Figure 2 shows a four-bar linkage. Body 1 is the fixed link or the ground, body 2 is the crankshaft OA, body 3 is the coupler AB, and body 4 is the rocker BC. Using the complex-algebra approach, obtain an expression for the angular velocities of the coupler and the rocker in terms of the angular orientation and angular velocity of the crankshaft. Assume that the angular velocity of the crankshaft is constant and is equal to...

Example 2.11: The 2-inch crank on the wiper mechanism in Figure 2.85 rotates counterclockwise (CCW) at 15 rpm and decelerates at 5 rad/s2. At this instance, 0 = 50°. All dimensions are in inches. Use the Grashof's Criterion to determine the relevant type of the four-bar mechanism. Can the driver link rotate fully? Analyze the mobility of the machine to know its degrees of freedom. Where is a good place to locate the actuator? Use the position analysis to determine...
