The angular velocity and angular acceleration of the body. Rate and acceleration of a point a rigid body rotating around a fixed axis. Angular velocity of the body. (The expression rate of the point of a rotating body in the form of vector product.) Plane (flat) of a rigid body. Plane motion of rigid body motion and a plane figure in its plane. The equations of motion of a plane figure.
Decomposition of the motion of a plane figure in the progressive movement together with the pole and rotation around the pole: independence of the angular velocity of the choice of pole figures. To determine the rate of any point of the figure as the geometric sum of the velocity of the pole and the speed of this point by rotating the figure around the pole. A theorem on projections of velocities two points of the figure (body). Instant center velocities. Determining the velocity of points of a plane figure with the instantaneous center of speeds. Complex (compound) move the point. Absolute and relative motion of the point; Portable movement. A theorem on the addition of velocities.
Theorem on the addition of the acceleration in the figurative and metaphorical translational rotational movements; Coriolis acceleration and its calculation. Dynamics Dynamics is the section theoretical mechanics that studies the mechanical motion of material bodies, depending on the reasons causing them. In the static studied the problem of reducing power systems to their simplest form and the relative equilibrium material bodies in the kinematics discussed the problem of the geometrical characteristics of the mechanical motion. In the dynamics – the main section of the course – on the basis of information from the statics and kinematics and dynamics of special laws solve the problem of the connection strength and movements. Any mechanical motion of material bodies occurs over time in space. There is no movement of material objects outside space, and also there is no movement out of time. Time and space can not exist apart from and independent of the motion of material bodies. Thus, they are forms of existence of matter in motion. Material point is called the material body, the rotational movements which, compared with the translational, can be neglected. Thus does not necessarily mean a material point of the body is very small sizes. A solid body moving steadily, is regarded as material point. A material point is a point at which levied connection, limiting its movement. Laws describe the dynamics of mechanical motion of material bodies in relation to the so-called "fixed" or "Absolute" coordinate axes relative to the axes, which are moving steadily and uniformly with respect to the fixed (inertial axis).
