Kinetics in Angular Motion
Published in Emeric Arus, Biomechanics of Human Motion, 2017
The conditions for a body to be in equilibrium under angular motion have been stated earlier. Now, how can we calculate equilibrium? The majority of motions involve torque. But torque involves moment of inertia, lever(s), and angular acceleration. The torque is apparent when the body has contact with a force and also has contact with the center of the rotation that is connected to the line of action where the force is activated. In this case, we speak about torque, which we will describe later.

Torque is equal to the product of the force applied to a lever and the perpendicular distance from the line of action of the force to the axis of rotation: () T=(F)(r)

In addition to the magnitude of the total force, we need to know its line of action. Since all the elemental forces are perpendicular to the plane, their total is also perpendicular to the plane. It remains to determine the point at which its line of action meets the plane. This point is known as the centre of pressure (although centre of thrust might be a better term).

Lifting of surface plate through normal reaction forces is required support block and it is placed underneath whereas vacuum suction forces via suction cups are placed above the flat plate to lift the surface as depicted in Figure 6. Both the forces have the same line of action, difference being in the point of force application. The finite element analysis was then performed for the various Taguchi Combinations by constraining areas corresponding to the suction cup contact area at the pick positions and by applying vertical pressure of 0.420 bar at each constrained zone as depicted in Figure 7. The software packages used were Hyper mesh and Ansys Mechanical APDL. After having performed the FEA examinations, the maximum deflection achieved in each Taguchi Combination were checked.
