A power hacksaw used to cut metal, Link 5 pivots at O5 and its weight forces the saw-blade against the workpiece while the linkage moves the blade (link 4) back and forth within link 5 to cut the part. a.Sketch its kinematic diagramb. Determine its mobility and its type (i.e. is it a fourbar, a watts sixbar, a stephenson’s sixbar, or what?)c.Use reverse linkage transformation to determine its pure revolute-jointed equivalent linkage
