En lo personal este curso es muy bueno, soy estudiante de la universidad veracruzana y con este curso he mejorado mi conocimiento me ayudo a comprender mas sobre la mecánica y comportamiento de las estructuras que son sometidas esfuerzos para conocer su comportamiento.
A very useful course for getting a strong foundation in strength of materials course. Definitely recommend to all who wants to learn it. Looking forward to future courses. Dr. Whiteman is outstanding.

This is a great course. I only wish a different problem book was used - it contains errors and the answers are not provided. Another solution is for the course staff to solve each problem first and publish their answers.
