Describe with the aids of diagrams the three methods of kinetic analysis methods of a particle in plane motion. A mechanical device shown in Figure Q3(b) is in vertical plane which consists of two balls of mass 3 kg each, a central collar of mass 4 kg and a spring of stiffness k = 650 N/m which is uncompressed when = 0 from which the mechanism is released from rest. Ignoring the mass of all the links and friction in all the hinges at the joints, determine when = 60 the velocities of the balls and the collar. If a spring of the same undeformed length but with higher stiffness is used, evaluate its effect on the speed of the collar and justify the answer using the dynamic fundamental. 3 kg 4 kg 200 mm 3 kg 200 mm 300 mm Figure Q3(b)
