Paperback. Condición: New. Print on Demand. This book presents an analysis of rail steel endurance properties, with a specific focus on the comparison between standard molds and sink-head molds of the Gathmann type. The author conducts fatigue tests on 11 heats of steel, some of which were cast in standard molds and others in sink-head molds, to assess their resistance to repeated stress. The results of these tests indicate that the endurance limit of steel from 100-pound rails varies from approximately 43,000 to 59,000 lbs/in2, and that the endurance ratio ranges from 37 to 44%. In general, rails rolled from sink-head ingots had higher endurance limits. The author also explores the effects of overstressing and understressing on the endurance limit of rail steel, finding that overstressing decreases the endurance limit while understressing increases it. This book provides valuable insights into the fatigue properties of rail steel and their implications for the prevention of rail failures, making it a significant contribution to the field of railroad engineering.

Softcover. Condición: Fair. B&W photos Ilustrador. (NAP). Stapled card covers. Hard-to-find item. ***INCLUDES THE PINWHEEL TOOL! (Photo is of actual items.)*** I've marked the condition as "Fair only" because both book and tool are worn (the tool is functioning, though), and the book is grubby, with ***some markings in red ink***, and some staining inside the covers. The binding is firm, though.
