Depending upon the preparation and interest of the In Sec. It is essential, sum of a translation and a rotation. This however, that the significance of Eqs. The instructor should note the distinction made Section The instructor forces i. The it cannot be used to determine accelerations. Students should be warned concept of Coriolis acceleration to three- against any unwarranted assumptions dimensional motion.
It Chapter 16 presents an analytical method for the Plane Motion of Rigid Bodies: determination of velocities and accelerations Forces and Accelerations based on the use of a parameter. This chapter is devoted to the plane motion of Section Cases involving the plane determination of Coriolis acceleration in plane motion of nonsymmetrical bodies and, more motion.
To make the concept of Coriolis generally, the motion of rigid bodies in three acceleration as intuitive as possible, an example dimensions are considered in Chap. If the involving the motion of a collar on a rotating determination of mass moments of inertia has rod is given on page It should be kept in not been covered in the previous statics course, mind, however, that Coriolis acceleration does the instructor should include material from not depend upon the existence of an actual slab Secs.
It will from the second part of Chap. There lies the fundamental difference between the In Sec. This result, which is illustrated G to the kinematics of rigid bodies in three in Fig. However, they motion of a rigid body three-dimensional as should be included in a course covering the well as plane motion.
It is shown that the have magnitude and direction, the rotations are external forces acting on a rigid body are not vectors see also Sec. As noted in Sec. It should be emphasized that in transmissibility Sec. To avoid drawing two separate Prob.
However, to understanding of the kinetics of the motion. Translation, centroidal rotation, 3 The method used divides the solution of and plane motion consisting of a translation and a problem into two main parts, one in which the an unrelated centroidal rotation are considered kinematic and kinetic characteristics of the first, since they are the simplest ones to analyze.
In this way the techniques of rotation, rolling motion, and other types of each separate field can be used most efficiently. Problems involving systems of For example, moment equations can be written rigid bodies have been included at the end of to eliminate unwanted reactions, just as it was this chapter, with either one degree of freedom done in statics; this can be done independently Probs. The instructor should stress the fact that, in spite of 4 By resolving every plane motion even a the different kinematic characteristics of these non-centroidal rotation into a translation and a various motions, the approach to the kinetics of centroidal rotation, a unified approach is the motion is consistently the same: all obtained, which will also be used in Chap.
This approach is a basic one, which can be applied effectively throughout the study of Since the approach used in this text differs from mechanics in advanced courses as well as in others in the emphasis placed on the direct elementary ones. The expressions for the work of a of finite magnitude applied for a finite time or couple and for the kinetic energy of a rigid impulsive forces applied for a very short time body are derived in Secs.
Using interval, students are told to draw three separate the results obtained in Sec. The momenta of a rigid mass center. If students used in preference to special formulas. Indeed, then consider the components of the vectors it follows the basic idea of resolving every involved, they obtain relations between linear plane motion into a translation and a centroidal impulses and linear momenta. If they consider rotation. If, by It is shown in Sec. The advantages derived from this approach can be summarized as follows: In the second part of Chap.
The solution, a method based directly on a approach used is different from that of most fundamental principle and which can be used elementary textbooks. Ready-to-use formulas safely under any conditions. It particles are directly applicable to the system of is unlikely, for example, that students will particles forming a rigid body and can be used forget an impulsive reaction at a fixed support.
It is shown in Sec. In Chap. Since this will not be the case, however, if students are requires the use of mass products of inertia, as instructed to write separate equations involving well as the use of mass moments of inertia, the either components or moments, as they did in instructor should cover Secs.
No special In Secs. D'Alembert's principle is extended to the case of three-dimensional In this chapter, the restrictions imposed in motion by showing that the external forces are preceding chapters e. It is represented by Equations At this energy still apply in the case of the motion of a point Eulerian angles are introduced.
It should rigid body in three dimensions. The special case of steady of the kinetic energy of the body. Several be approximated by a simple harmonic motion.
