Henri Tresca
Henri Édouard Tresca (born October 12, 1814 in Dunkirk ; † June 21, 1885 ) was a French engineer who taught mechanics at the Conservatoire National des Arts et Métiers (CNAM) in Paris .
Tresca was involved in the design of the standard measuring stick , which is still kept in Paris today . For reasons of thermomechanical stability, he had this made from a combination of 90% platinum and 10% iridium with a cross-shaped cross-section.
The shear stress hypothesis, which deals with the mechanical strength of materials, goes back to Tresca .
Tresca's reputation as an engineer was so good that Gustave Eiffel placed him number 3 on a list of 72 scientists and engineers who are said to have made the construction of the Eiffel Tower possible.
In 1872 he was accepted into the Académie des Sciences .
