Page iii - ... support bolted to a railway sleeper; material all ready to hand and requiring little skill for adjustment. No need for the lecturer to interrupt the course of his explanation while spinning the wheel with a stick. Perry says in his popular treatise on the Spinning Top, p. 69: „I believe there are few mathematical explanations of phenomena which may not be given in quite ordinary language to people who have an ordinary amount of experience.

Page 53 - ASN ....... (4) _ 10,860 The numerical coefficient might evidently be taken as 6.08 without material error. Thus for each ratio of volumes there will be a numerical coefficient by which if the piston area and stroke in inches be multiplied the product will be the work of the explosion stroke in foot-pounds. If we have some other ratio of volumes and are not satisfied with the approximate result given by (4), we may calculate the numerical coefficient for the particular case. We may find the ratio...

Page 16 - Find the weight of one cubic foot of air at any pressure and temperature: Let W equal the weight required.
Page 14 - If we take the pressure in pounds per square inch and the volume in cubic feet, the constant (C) for air at 62° is about 193.
