Methods of handling various types of steel evolve constantly across the areas of hardening, annealing, and tempering and Oberg's 'Heat-Treatment of Steel' has remained important to understanding our methods up to the modern day. The uses of new alloys and materials necessitates creativity and invention. This book covers the underlying rationale of the methods used and as such has become timeless in a world of constant change. Alongside advice ...

Excerpt from Strength of MaterialsIt may be said, in a general way, that when designing machinery the designer must take into consideration two main factors. One is to so design the mechanism mechanically that the various motions required can be obtained by means of the machine. The other is to so proportion the parts that they will be strong enough to do the work for which they are intended Without breakage and, in most cases, without distort...
