Sinossi

Excerpt from Testing of Methods for the Determination of Young's Modulus by Bending: Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Arts in Physics in the Graduate School of the University of Illinois, 1916

Many attempts have been made to determine the exact relation between the stress and strain of a body. Among the early scientists this field of investigation was leading in thought and effort. As thought and reason did not have the dominant influence, men were handicapped in not having the benefit of a scientific past as men have today. Consequently, they proceeded on very far fetched assumptions. From common experience they noticed that a beam would bend under a stress but did not recognize a definite relation between the bending and the force producing it. This, however, was a minor part in this vast field. What took place within the bent ohject was a matter of serious thought and controversy. It took nearly a century and a half before men discovered and were able to calculate the exact relation between the longitudinal and lateral forces within the strained object. Theoretical and experimental investigations went hand in hand until at present there is a vast wealth of data showing the relation between stresses and the strains and also the phenomena which takes place within the distorted body. So many methods have been developed to show these relations that one has to choose those best adapted to his conditions.

It is the purpose of this investigation to determine what methods are best adapted for use in an advanced laboratory course to show the relation between stresses and strains.
