Problem 2.3 Loci of Points – KL is a crank of 35 mm length revolving in a clockwise direction. LM is a rod connected to the crank at the point L by turning pair and rod LM is constrained to pass through the guide at O1 called trunnion. Draw the loci of points P and M for one revolution of the crank KL. The point P is 40 mm from L on the rod LM. Length of LM is 120 mm. Point O1 is 80 mm on the right and 30 mm below the point K.

Problem 2.2 Loci of Points – O1ABO2 is a Four Bar Chain with the link O1O2 as the fixed link. Driving crank O1A is 30 mm long. Driven crank O2B is also 30 mm long. Connecting link AB is 80 mm long. Distance between O1 and O2 is 80 mm. Two cranks are revolving in opposite direction. Draw the loci of points M and N for one complete revolution of the driving crank. The point M is the mid-point of the connecting link AB and the point N is 30 mm from B on AB extended.

Problem 2.1 Loci of Points – OBA is a simple crank chain. OB is a crank of 35 mm length. BA is connecting rod of 90 mm length. Slider A is sliding on a straight path passing through the point O. Draw the locus of the mid-point of the connecting rod AB for one complete revolution of the crank OB.
