Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1889 edition. Excerpt: ...to two non-parallel and non-intersecting locors, Q and R, either of these, say Q, may be resolved into two components, one component being equal and opposite to R (i.e.: R). This component forms with R a couple, and the whole set is now reduced to a couple and a single locor, which is in general oblique to the axis of the couple, but by the previous method can be further reduced to a couple and a locor parallel to the couple axis. It is, however, questionable whether there are many cases in which there is any practical advantage to be gained by substituting a couple and locor (which together really mean three locors) for a system of two single non-intersecting locors. Two oblique non-intersecting locors may always be reduced to two other perpendicular non-intersecting locors. Thus, in Fig. 62, let a b be the one locor in the plane of the paper and General cd be the projection on the same plane of the other. This rtor latter can be resolved at the point c where it cuts the reducti plane of the paper into two components, of which the projection c d is one and the other is perpendicular to this plane. c d and a b can be added, the sum being a locor ef in the plane of the paper. The system is now reduced to ef in this plane and the vertical component of the second locor perpendicular to same plane and passing through c. One is at liberty to choose any plane that may be most convenient for this reduction, and for this reason among others this solution may in many instances be more convenient and useful than the reduction to a couple and a perpendicular locor, for which latter there is only one definite plane possible for the couple. CHAPTER IX. KINEMATICS OF MECHANISMS. 1. In this chapter there are dealt with the relations between the velocities and..
