ENG06027 2013 Engineering Physics
The student will learn the basic laws of Physics and Chemistry pertaining to Mechanical & Electronic Engineering including defining the standard units of measurement, forces, and the properties used in modern day engineering. The student will be able to explain experimentation, vector addition, how heat is transferred, radioactivity, thermal expansion, the structure of atoms, efficiency calculations, fluid pressure, and some wave theory.
This module is taught by a number of lecturers and includes many real life situations where the topics covered are used.
On completion of this module the learner will/should be able to;
Be able to solve various exercises involving physics, such as heat transfer and thermal expansion using and manipulating the correct units of measurement
Be able to explain the structure of atoms, balance simple chemical equations, and be able to explain natural radioactivity and solve exercises relating to radioactivity.
Be able to determine the efficiency of various simple machines, explain their operation and determine their mechanical advantage (force ratio) and velocity ratio (movement ratio)
Be able to explain properties such as temperature and pressure and be able to use the gas laws to determine values for properties which undergo change.
Be able to explain wave propagation, sound and light and be able to explain simple reflection, refraction, diffration, and interference of waves, plus use the doppler effect to solve for changes in perceived frequencies.
Module Assessment Strategies
This course is designed to be a mixture of continuous assessment, practical experimentation, and terminal examinations. There is a quiz each week on IT Sligo's learning management software, plus every week the students attend for a practical experiment. There is also the possibility to have minor assessments during the semester.
A terminal examination will be held at the end of the semester and accounts 70% of the overall mark.
Repeat assessment will be by way of sitting another examination on the subject. Alternatively, at the discretion of the lecturer, assignemnts covering the deficient areas of the course may be set.
