Figure P3-4 shows a non-Grashof fourbar linkage that is driven from link O2 A. All dimensions are in centimeters (cm). (a) Find the transmission angle at the position shown. (b) Find the toggle positions in terms of angle AO2O4. (c) Find the maximum and minimum transmission angles over its range of motion by graphical techniques. (d) Draw the coupler curve of point P over its range of motion.
3-16
Draw the Roberts diagram for the linkage in Figure P3-4 and find its two cognates. Are they Grashof or non-Grashof?
3-17
Design a Watt-I sixbar to give parallel motion that follows the coupler path of point P of the linkage in Figure P3-4.
3-18
Add a driver dyad to the solution of Problem 3-17 to drive it over its possible range of motion with no quick return. (The result will be an 8-bar linkage.)
Design a fourbar mechanism to give the three positions of coupler motion with no quickreturn shown in Figure P3-2. (See also Example 3-5.) Ignore the points O2 and O4 shown. Build a cardboard model and determine the toggle positions and the minimum transmission angle from the model. Add a driver dyad. (See Example 3-4.)
