Consider the motion of the piston discussed in Example 1.6–1. The piston stroke is the total distance moved by the piston as the crank angle varies from 0° to 180°.

a. How does the piston stroke depend on L₁ and L₂?

b. Suppose L₂ = 0.5 ft. Use MATLAB to plot the piston motion versus crank angle for two cases: L₁ = 0.6 ft and L₁ = 1.4 ft. Compare each plot with the plot shown in Figure 1.6–3. Discuss how the shape of the plot depends on the value of L₁.
