Previous knowledge expected

Mathematics and physics on high school level
Objective (expected results of study and acquired competences)

The students possess the knowledge and computational skills required to analyse and calculate physical problems relevant to wood and natural fibre technology in the fields of mechanics, energy, thermodynamics and electricity. For example, upon successful completion of the module, they will be able to
- use and convert physical units correctly
- describe different types of motion in basic terms and calculate motion parameters
- calculate forces and torques, and the resulting accelerations and angular accelerations
- determine the mechanical work and energy associated with forces and torques
- calculate support reactions and internal forces in a beam
- state the conservation laws of mechanics and apply them to physical problems
- Calculate the power output of run-of-river power stations, pumped-storage power stations and wind farms
- State the internal energies and heat capacities of gases, solids and liquids
- Calculate the heat capacity of and heat conduction in damp wood
