Course Highlights

This course features an online version of the textbook for the course (Engineering Mechanics for Structures, written by Professor Louis L. Bucciarelli) in the readingssection. This course also has virtually all of its materials online, including real toolsand data, interactive exercises, and design exercises in the assignments section.

Course Description

1.050 is a sophomore-level engineering mechanics course, commonly labelled "Statics and Strength of Materials" or "Solid Mechanics I." This course introduces students to the fundamental principles and methods of structural mechanics. Topics covered include: static equilibrium, force resultants, support conditions, analysis of determinate planar structures (beams, trusses, frames), stresses and strains in structural elements, states of stress (shear, bending, torsion), statically indeterminate systems, displacements and deformations, introduction to matrix methods, elastic stability, and approximate methods. Design exercises are used to encourage creative student initiative and systems thinking.


The aim is to introduce students to the fundamental concepts and principles applied by engineers - whether civil, mechanical, aeronautical, etc. - in the design of structures of all sorts of sizes and purpose. We build upon the mathematics and physics courses of the freshman year, extending Newtonian Mechanics to address and understand the elastic behavior of trusses and frames, beams and cylinders. We aim also to engage students in the formulation and resolution of open-ended, design-type exercises, thereby bridging the divide between scientific theory and engineering practice.
