Abstract
THE “notes” issued by Mr. Thomas deal with a fairly wide range of dynamical problems, and there are hundreds of excellent exercises, but this is all one can say in their favour. The diagrams are very roughly drawn, and the whole style of the book is reminiscent of the student's lecture notes. Thus one must object to a statement like “The engineer unit of mass is M/g, where M is the mass in pounds, and g= 32.2”; or “The various forms of energy are: potential, kinetic, heat, electrical, and chemical”; or “Neglecting the effect of the axle, the moment of inertia of a flywheel is MR2/2,” without saying anything about the construction of the flywheel; or “Iz=Ix + Iy” in dealing with moments of inertia, without mentioning that this refers to a plane lamina.
