1.7 Figure P1.7 shows another type of elliptical trainer machine. The mechanism is a planar linkage that includes a slider joint. There are linkages on both sides of the machine. The linkage on the right is a mirror image of the one on the left and the linkages are connected together so that they are always $$180^{?}$$ out of phase with each other. For the left side linkage identify the moving joints and links. There is a handle that rotates about a fixed pivot. There is also a foot pedal that floats in that it is not connected to the frame of the machine. Sketch the topology of the linkage. How many links and joints are there? How many binary links? How many ternary links? Identify any joints that perform complete rotations as the mechanism is cycled.
