FIGURE P3-13
Problems 3-46 to 3-48
3-46 Design a fourbar linkage to move the object in Figure P3-13 from position 1 to 2 using
points A and B for attachment. Add a driver dyad to limit its motion to the range of
positions designed making it a sixbar. All fixed pivots should be on the base.
3-47 Design a fourbar linkage to move the object in Figure P3-13 from position 2 to 3 using
points A and B for attachment. Add a driver dyad to limit its motion to the range of
positions designed making it a sixbar. All fixed pivots should be on the base.
3-48 Design a fourbar linkage to move the object in Figure P3-13 through the three positions
shown using points A and B for attachment. Add a driver dyad to limit its motion to the
range of positions designed making it a sixbar. All fixed pivots should be on the base.
