#### Synopsis

Experimental mechanics: particle dynamics, experimentation, modelling. Kinematics: position, velocity and acceleration; analysis and applications; translational and rotational motion of free and constrained forces, their origin and significance; energy dissipation in mechanical systems; mass moment of inertia; linear and angular momentum. Analysis and synthesis of planar mechanisms. Fundamentals of mechanical vibrations. Strength of materials: stress and strain in 2D and 3D, Mohr circle. Equilibrium and compatibility equations; Hookes law. Simple failure criteria. Shear force and bending moments, moments of area, deflection of beams, buckling.

#### Objectives

On completion of this units students should be able to:

- understand how the observed phenomenon of motion can be analyzed mathematically

- 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

- apply Newton's laws to the dynamics of motion

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

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

- calculate bending moments and shear forces

- understand Hookes law and failure criteria in elastic materials

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

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