Print on Demand. This book documents the author's investigation into the temperature coefficients of metals and alloys relevant to their use as elastic elements for aircraft and instruments. The author expands on the work of Brombacher and Melton but instead of the torsion pendulum they used, the author employs helical spring specimens. The results of the author's novel approach yield data on the temperature coefficients of both the rigidity modulus and Young's modulus of elasticity from the same specimen of a given material. The study is unique in that the experiments measure both the initial and changing deformation of the springs as temperature varies, and account for internal stresses within the springs themselves as well as experimental error from a number of sources. Also unique is the extrapolation of data to zero initial de- or extension. The book concludes with the measured temperature coefficients of rigidity and Young's modulus of elasticity at 0° C for 31 alloys and pure metals and the thermal coefficient of expansion for each of those materials. The insights and methods presented in this book remain valuable for scientists and engineers working on elastic elements for instruments and other applications. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.…

Brombacher and. Me1ton used a torsion pendulum to determine the temperature coefficient of the modulus of rigidity and the effect of stress and heat treatment 011 both the modulus and the temperature coefficient. This method has serious disadvantages. In selecting a more suitable experimental method consideration was given to the practical necessity of obtaining temperature control by means of a liquid bath and to the desirable possibility of obtaining the data on both moduli from the same specimen of a given material. This led to the use of helical spring specimens. Two springs of the given mate rial and of the same design were coupled together and (a) stressed in tension to obtain the temperature coefficient of the rigidity modulus and (b) stressed in twist to obtain the temperature coefficient of Young' 8 modulus of elasticity. While under each type of stress the change 111 the deformation of the springs of the coupled system was measured as the temperature of one of the springs was varied while that of the other spring was maintained constant. The use of two springs was necessary to eliminate lateral vibration and to a large extent the effect of elastic afterworking or drift. If the two springs were exactly alike the drift would not change the deflection of the springs since their actions opposed each other.

Other policies
Please note that we cannot accept cancellation requests once an order has been placed.
All Forgotten Books titles are printed on demand. The moment an order is submitted, it is automatically transmitted to our distributor and then forwarded to the printer, where it enters production. This process begins within minutes and is entirely automated.
A cancellation, however, is a manual, multi-step request that must pass through several systems. By the time such a request reaches the appropriate stage, the book has almost always been printed, packed, or already dispatched, which makes cancellation impossible.
For this reason, we kindly ask that you double-check the title, edition, and your shipping details before placing an order.
If you change your mind after ordering, you are welcome to return the book once it arrives, and a refund will be issued in accordance with AbeBooks’ return policy.
Please also make sure your address is correct before ordering as we will no be able to intervene and make changes before the book is shipped.
We can provide digital samples for all our print books ahead, so don't hesitate to reach out.
Returns
As a small publisher we do not have the facilities to resell returned books, so any returned book will be recycled. If the book is damaged or defective please continue with the return process, and thank you for letting us know so that we can improve our products. If you’re returning for another reason, however, please consider whether you could donate or gift the book instead so that it avoids the waste pile.
Thank you in advance!
