| Aims |
|
Teaching of fundamental notions of mechanics: cinematics of the material point and of rigid body, fundamental notions from the dynamics of the material point and of the rigid body. Application of the theory of differential and integral calculus theory and also of the theory of differential equations in the study of some special problems of mechanics. |

I. KINEMATICS:
1. Introduction. Fundamental notions. 2. Kinematics of the material point: path, motion equations, the velocity and acceleration of material point. Kinematics in Cartesian coordinates, with respect to the Frenet orthogonal axes, and in curvilinear coordinates. Areolar velocity. 3. Kinematics of the solid rigid body: Euler's angles. Motion's equations. Poisson's formulas. The velocity and accceleration distributions of solid body. The motion of the solid body with a fixed point. The general rigid-body motion. The plane-parallel motion of the rigid body. 4. The relative motion of the material point. The velocity and acceleration distributins. Coriolis' theorem. II. DYNAMICS OF MATERIAL POINTS: 1. The free material point. Principles of Newtonian mechanics. The Newton equation. Equations and general theorems. Virtual work and the force function. Central forces. Newton's problem. 2. The motion of a material point with restrictions: the motion on a fixed curve and on a fixed surface (with or without friction). The mathematical pendulum. 3. Dynamics of the relative motion: the differential equation of the relative motion. III. DYNAMICS OF SYSTEMS AND RIGID BODIES 1. Centre of inertia (gravity). Momentum of inertia. Momentum of inertia with respect to parallel axes and axes which contain a given point. Ellipsoid of inertia (principal axes and directions). Equations and general theorems for the systems of material points. Virtual work of the exterior and inner forces. Prime integrals. The motion of a material system with respect to the centre of inertia. Konig's theorems. Equations and general theorems for the motion about the centre of inertia. 2. Dynamics of the rigid body. The motion of the rigid body with a fixed point. Kinematical energy and the kinematical torque. Applications to the Lagrange-Poisson case of motion. |
