In the 1700s, noted engineer James Watt devised and patented a mechanism for generating straight-line motion with a rotational input. In this mechanism, shown in Figure P11.4A, the center point of Link 3 will trace out a straight line in space as the input link (Link 2) rotates, as illustrated in Figure P11.4B. Originally designed for guiding the stroke in a steam engine piston, this mechanism is currently used to guide axle motion in automotive suspension applications. 1 Develop a working model of the Watt Straight Line Mechanism. Use a length of 8 inches for Links 2 and 4, and a length of 4 inches for Link 3. The distance between the fixed pivot points is 16 inches. (Note: This is considered a double rocker mechanism; the input link is not able to rotate through a full 360 degrees.)
