### Synopsis

Kinematics: position, velocity and acceleration; relative motion analysis and applications for particles and rigid bodies; Dynamics: translational and rotational motion of free and constrained forces, their origin and significance; equation of motion, principle of impulse and momentum, principles of work and energy; Analysis of planar motion. Fundamentals of mechanical vibrations. Strength of materials: stress and strain in 2D and 3D space; Hookes law; Shear force and bending moments, moments of area, deflection of beams; Equilibrium and compatibility equations; Stress and strain transformation; Mohr circle; Simple failure criteria; Elastic instability --- buckling.

### Outcomes

On completion of this units students should be able to:

1. understand how the observed phenomenon of motion can be analyzed mathematically

1. understand the concepts of position, velocity and acceleration as applied to the kinematics of particle and whole body motion and to be able to solve problems of translational motion

1. apply Newton's laws to the dynamics of motion

1. extend kinematics and dynamics to rotational motion and to be able to calculate mass moments of inertia for simple elements

1. understand the concepts of stress and strain and the Mohr circle as applied to structures

1. calculate bending moments and shear forces

1. understand Hookes law and failure criteria in elastic materials

1. calculate deflections in beams and buckling in columns using moments of area information

1. observe all of the above phenomena in the laboratory and to learn how to measure key variables.

### Assessment

Test/Class work: 30%
Examination (3 hours): 70%

Students are required to achieve at least 45% in the total continuous assessment component and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.
