The purpose of this module is to provide the student with the analytical tools to design specific mechanical systems, an awareness of the responsibilities of the mechanical designer, and an introduction to the design process. The student learns through a combination of lectures, tutorials, laboratories, group assignments, formative assessments, and self-directed learning the skills, knowledge, and professional attitudes, necessary to work with others on the design of mechanical systems. This module applies analytical techniques to the design of mechanical systems. This is achieved by reducing machinery to a series of typical mechanical components and conducting a series of calculations in order to optimise one or more critical variables within the design constraints.
