1 (a) Find the number of degrees of freedom for the spatial linkage of Figure P1.1. This open-loop|kinematic chain includes cylindrical, prismatic, and spherical pairs. FIGURE P1.1 (b) Figure P1.2 is a schematic representation of a piece of construction machinery. It has two hydraulic cylinders (links 1 and 2, and links 6 and 7), which may be considered cylindrical pairs. The other pairs are revolute joints, including a double revolute joint where links 2,3, and 8 meet. Find the number of degrees of freedom if this linkage is treated as a spatial linkage. ) Find the number of degrees of freedom if the linkage of Figure P1.2 is treated as a planar linkage. 1) Referring to Figure P1.2, indicate the conditions that must be met for the planar linkage assumption to be valid.
