Prerequisite Modules:

Rationale and Purpose of the Module:

To provide students with a basic knowledge of the fundamental principles underlying engineering mechanics.

Syllabus:

Units, Newton's Laws, Statics - condition for equilibrium, resolution of forces (polygon and components of forces), free body diagrams, friction on an inclined plane, Varignon's Theorem, Moments, Bending Moment Diagrams, Introductory stress (direct, shear, strain, Young's Modulus, principle of superposition, torque), Frameworks. Dynamics - linear motion angular motion, relative motion, Work, Energy, Newton's law of impact.

Learning Outcomes:

Cognitive (Knowledge, Understanding, Application, Analysis, Evaluation, Synthesis)

Given a system of forces and moments, determine a single resultant force and moment which is equivalent. Given a picture of a structure showing the loads and supports, draw a free-body diagram of either the whole structure, or a component part of it, and solve for the support reactions and the bending moment distribution. Given a picture of a plane truss or framework showing the loads and supports, determine the axial force in each member and whether it is in tension or compression. Apply equations for straight-line motion to solve problems with constant acceleration Apply Newton's second law to a point mass object to determine the acceleration or force required to achieve a stated acceleration.

Affective (Attitudes and Values)

Acknowledge the use and accuracy of engineering approximations Value the contribution of first order design calculations using first principles in engineering

Psychomotor (Physical Skills)
