| CE 241 Mechanics of Materials | (4+1+0)4 |
|||
Concept of modeling and basic principles. Rigid bodies. Equivalent systems of forces. Equilibrium of rigid bodies. Analysis of two-dimensional trusses. Normal and shear forces and moment diagrams in one-dimensional structures. Mechanical properties, static and dynamic loading. Elastic stresses and strains due to axial and shear loading and bending and torsional moments. Transformation of stresses and strain, multidimensional stress-strain relations. Stresses due to combined loading. Failure criteria. Deflection of beams. Elastic stability. Elastokinetics. |
||||
| Couse Objectives | ||||
This course is designed to introduce basic principles of statics for rigid and deformable bodies. The main objective is to help the students develop an intuition for equilibrium, properly constrained systems, and deformation under external loadings. It is also anticipated that the theory and design approach for the mechanics of deformable bodies will help prepare the students for complex systems that will be encountered in advanced design courses. |

| Design Content | ||||
This course introduces the basic principles of mechanics with direct implications and applications to design of structures. Estimated design content is 30%. |
||||
| Computer Usage | ||||
The students are encouraged to use either commercial software or to write their own codes for analysis of truss systems. A particular case where the students may require computer usage is the non-mandatory design project. |
