Base Knowledge
Vectorial and differential calculus; basic notions of mechanics (movement, force, energy)
Teaching Methodologies
Theoretical classes are based on concepts description supported by practical examples. Theoretical practical classes are devoted to practical problem solving. Laboratory classes include the execution of experimental work.
Learning Results
This course main goal is to create the ability of understanding and design mechanical gears built on rigid bodies.
