Module Title:Mechanics of Machines 2
Language of Instruction:English
Credits: 10
NFQ Level:6
Module Delivered In 2 programme(s)
Teaching & Learning Strategies: The module will be delivered using lectures, tutorials and laboratory sessions to illustrate the concepts under study.
Module Aim: • To provide the student with a broad knowledge of the external effects of forces applied to particles, as evidenced by the change of motion produced. • To provide the student with a broad knowledge of the internal effects of forces applied to members in structures and mechanisms, as evidenced by the stresses and deformations produced. • To provide the student with a foundation for subsequent modules in Mechanics of Machines and other related modules.
Learning Outcomes
On successful completion of this module the learner should be able to:
LO1 Apply and solve formulae involving the interaction of the motion of an object and the forces and torques to which it is subjected;
LO2 Apply and solve formulae involving the concepts of direct stress and Modulus of Elasticity, shear stress and Modulus of Rigidity and their applications such as torsion in solid and hollow shafts and in belt drives and couplings.
LO3 Apply and solve formulae to determine the shear force and bending moment distributions resulting from the loading of a structural element such as a simply-supported beam or cantilever ;
LO4 Apply and solve formulae to determine the forces in the individual members of a loaded truss or framework;
LO5 Contribute effectively, as an individual and as part of a group, to the planning and realization of investigations in a laboratory environment into the effects of applied forces on components.
