Content and learning outcomes
Course contents
Rigid body kinematics. General dynamic equations for a system of particles. General 3D motion of a rigid body. Analytical mechanics with application to systems of particles, rigid bodies and systems of rigid bodies. In particular Lagrangian methods including generalized coordinates, velocities, momenta and forces, cyclic coordinates and conservation laws.
Applications include dynamics of planar multibody mechanisms, gyroscopic effects in 3D-motion, impact problems, linearization and coupled oscillations, normal modes. Problems are treated with modern computational methods including symbolical (Maple) and numerical treatment.
Intended learning outcomes
After the course the students should be able to:
Find and combine moments of inertia and construct inertia tensors.
Use the Newton-Euler vector formalism to solve rigid body problems.
Calculate the generalized forces for holonomic few-body systems.
Calculate Lagrangian functions for holonomic few-body systems, by hand and by using computer algebra.
Derive Lagrangian equations of motion for holonomic few-body systems, by means of computer algebra when necessary.
Solve these equations, numerically as well as analytically, for a number of standard problem types, including impact problems and coupled oscillation problems.

Examination and completion
If the course is discontinued, students may request to be examined during the following two academic years.
Grading scale
A, B, C, D, E, FX, F
Examination
- INL1 - Assignments, 2,0 hp, betygsskala: P, F
- TEN1 - Examination, 5,0 hp, betygsskala: A, B, C, D, E, FX, F
Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.
The examiner may apply another examination format when re-examining individual students.
Other requirements for final grade
Home assignments and written exam.

Ethical approach
- All members of a group are responsible for the group's work.
- In any assessment, every student shall honestly disclose any help received and sources used.
- In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
