Description

This unit provides a thorough coverage of engineering mechanics including study of statics, dynamics, kinetics, etc. and applications of these to mechanical systems.

Prerequisite Rule

Students must pass 1 unit from SCP1111

Equivalent Rule

Unit was previously coded ENS1101, ENS2113, ENS5125

Learning Outcomes

On completion of this unit students should be able to:

1. Analyze the forces on structures including distributed forces and frictional forces
2. Apply knowledge of kinematics, inertia and gyroscopic motion to the design of simple mechanical systems.
3. Draw free-body diagrams to accurately describe rigid and kinematic mechanical systems.
4. Solve a wide variety of engineering mechanics problems in free space mechanics and general planar motion.
5. Use the conditions of static equilibrium to resolve the forces and moments on a structure.

Unit Content

1. Basic concepts of mechanics and vectors.
2. Distributed forces: center of mass, centroids of lines, areas, and volumes, external loading and reactions acting on beams, internal shear force and bending moment as functions of location along the beam.
3. Dry friction and design of belt drives.
4. Equilibrium in two and three dimensions: system isolation and the free-body diagram, equilibrium conditions.
5. Planar kinematics of rigid bodies: rigid body motion, rotation about a fixed axis, relative-motion analysis.
6. Planar kinetics of rigid bodies: force and acceleration; moment of inertia, planar kinetic equations of motion, general plane motion, work and energy, kinetic energy, work and energy.
7. Structures: plane trusses, method of joints, method of sections, space trusses, frames and machines.
8. Three-dimensional dynamics of rigid bodies: rotation about a fixed point, fixed-axis rotation, parallel-plane motion, gyroscopic motion, momentum and energy equations of motion.
9. Two and three dimensional force systems: rectangular components, moment and couple, resultants.
10. Vibrations; undamped free vibration, energy methods, undamped forced vibration.
11. Virtual work: method of virtual work, active-force diagram, virtual displacements, degrees of freedom, potential energy and stability.
