... where the angular displacement ⌬ must be measured in radian units and not in degrees. The fundamental unit of angular measure is the radian, because it is defined as the ratio of the arc length s to the radius r as ⫽ s/r, and is a pure number with no units. This definition of an angle in radians ...

Pinned or Hinged support
... Consequently, a pin support is capable of developing a force reaction with both horizontal and vertical components (HA and RA), but it cannot develop a moment reaction. At end B of the beam (Fig. a) the roller support prevents translation in the vertical direction but not in the horizontal direction ...

Precession
Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. In other words, the axis of rotation of a precessing body itself rotates around another axis. A motion in which the second Euler angle changes is called nutation. In physics, there are two types of precession: torque-free and torque-induced.In astronomy, ""precession"" refers to any of several slow changes in an astronomical body's rotational or orbital parameters, and especially to Earth's precession of the equinoxes.
