A slider-crank mechanism is one of the simplest and most common four-bar linkages. A oft- used example is the piston in a car engine. Given the diagram shown in Fig. 2, find and plot (for 5 s) the position, velocity, and acceleration of the piston given a constant angular velocity , and the properties given in Table 2. Note, this problem only has one degree of freedom. The position of the piston is completely defined by the angle 0₁. However, it is difficult to write the position vectors without considering the angle 92. The key is that there is a single constraint that equates 1 to 02.
