Annotation The study course studies the physical properties of wood, which include the geometric characteristics of wood, mass, density and thermophysical properties, as well as examines the mechanical properties of wood and the physical forces acting on wood. Various methods and equipment are used to determine the properties of wood. Students make samples of wood compounds, which are tested to test the acquired knowledge and obtain test results..

Goals and objectives
of the course in terms
of competences and skills 		The aim is to develop skills to analyse and evaluate existing wood and wood material products, as well as to improve knowledge on how to plan and design structures corresponding to the physical properties of wood and product type. The tasks are to provide and develop the ability to use theoretical knowledge. Improve skills by creating wood joints, structures and products in accordance with the strength data of physical properties, as well as to test connections, design models, layouts or products.
Learning outcomes
and assessment 		Knows the physical properties of wood and wood materials - the meaning of the properties and the impact on the visual, technological and practical needs of the product. - Test of theoretical knowledge in study tasks and exam.
Able to analyse existing wood products and wood construction models. - Test of theoretical knowledge in study tasks and exam.
Able to choose the appropriate material for the designed wood structures, the appropriate type of construction. - Test of theoretical knowledge in study tasks and exam.
Able to make designs, models, product samples. - The skills and ability to apply the knowledge of practical work in the practical design and development of structures are assessed in the laboratory work and in the final product of the study work - in a construction model, model or product - exam.
