Module Title:Mechanics of Materials 3
Language of Instruction:English
Credits: 5
NFQ Level:7
Module Delivered In 2 programme(s)
Teaching & Learning Strategies: The module will be delivered using lectures and tutorials with a mixture of presentations, example exercises, question and answer sessions, group discussions and online resources. Laboratory classes will be delivered to students working in groups to obtain experimental data with subsequent individual reporting/assessment.
Module Aim: To provide the student with an understanding 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 an understanding of the response of structures due to the properties of materials
Learning Outcomes
On successful completion of this module the learner should be able to:
LO1 Demonstrate the ability to analyse loads on mechanical components in order to determine the type and distribution of resulting reactions and the type and distribution of induced stress and strain.
LO2 Apply simplified models of stress and strain to representative systems in order to determine relationships between loads and the corresponding stress and strain.
LO3 Predict the behaviour and/or failure of mechanical systems subjected to loads.
LO4 Predict the behaviour of materials in service
LO5 Quantify, by calculation and experimental measurement, the characteristic response of mechanical systems.
