Aim
Engineering Mechanics, Basic Course is an introductory course in classical mechanics with the following objectives:

• aquire knowledge of and master the general principles and basic concepts of classical mechanics,

• become familiar with mathematical modelling of mechanical systems (particles and rigid body systems),

• learn to master problem solving for material bodies,

• learn how to use a modern engineering computer program in multibody dynamics.

Contents
Statics: Moment and force systems in 2 and 3 dimensions. Free-body diagrams and equilibrium of material bodies. Division of material into systems and partial systems. Section forces and equilibrium in lattices, beams and frames. Distributed forces, centre of mass and hydrostatics. Friction. Virtual work, potential energy and stability. The mechanics of wedge and screw.

Dynamics: Kinematics of particles in straight and curved motion, natural and polar co-ordinates.
Newton’s laws, momentum and impulse, moments of momentum and impulse moments. Collisions between particles. Use of a rotating co-ordinate system. Corioli’s theorem. Rigid-body motion in 2 dimensions following impulse, impulse moments and the inertia tensor. Simple oscillations.
