Module Aims
· To build on Applied Mechanics 2 and enable students to apply Kinetic and Kinematic principles to machine elements and systems· To introduce methods for synthesis of linkage for design applications in mechanisms and robotics

Learning Outcomes

On completion of this module, the student will be able to:

     Analyse the velocity and accelerations of planar mechanisms using mathematical & graphical methods (PO1, PO2)

     Determine the effects of forces & torques on 2-D systems, including the effects of rolling and sliding contact between bodies (PO1, PO2, PO3)

     Determine the power transmission and speed characteristics of simple & compound fixed centre and epicyclic gears (PO1, PO2)

     Explain the power transmission characteristics of friction based drive systems (belts & clutches) and apply the governing equations to determine the performance of such systems (PO1, PO3, PO6)

     Explain the concepts of static & dynamic balance of rotating shafts and determine the forces, couples and balance elements which for such (PO1, PO6)

     Explain and analyse rotating systems where gyroscopic couples are generated (PO1, PO2, PO6)

     Report practical results in a coherent and logical manner (PO5, PO6)
