Rotation Of A Rigid Body About A Fixed Axis

Rotation Of A Rigid Body About A Fixed Axis. Fixed Axis Rotation in Rigid Bodies Using Vectors This section presents relative motion using vector notation When moving from particle kinematics to rigid body kinematics we add the rotation of a body into the motion analysis process Some bodies will translate and rotate at the same time but many engineered systems have components that simply rotate about some.

PDF fileIf a point P is on a rigid body and that rigid body is rotated about some axis O which is a distance r away from the point P (see Fig 92 page 286) then the point P will move a distance s given by s = rµ (91) where the angle µ is in radians There are 2 radians in a full circle (= 360o) which makes one radian 573o.

Chapter 21 Rigid Body Dynamics: Rotation and Translation

PDF filetranslational and rotational motion about a fixed direction Because the body is translating the axis of rotation is no longer fixed in space We shall describe the motion separately and discover that the torque about the center of mass is equal to the change in the angular momentum about the center of mass.

CHAPTER 4 RIGID BODY ROTATION orca.phys.uvic.ca

PDF fileA rotating rigid body has kinetic energy because all atoms in the object are in motion The kinetic energy due to rotation is called rotational kinetic energy Copyright © 2008 Pearson Education Inc publishing as Pearson AddisonWesley Here the quantity I is called the object’s moment of inertia The units of moment of inertia are kg m 2 An object’s.

PDF fileChapter 13 Rotation of a Rigid Body Definition (HRW*) The centre of mass of an object or of a system of objects is that point which moves as though all mass were concentrated there and all forces were applied there eg As a hammer tossed through the air spins handle over head only the centre of mass follows the parabolic trajectory.
