EN221: Engineering Mechanics with Marine Applications I
EN221 Engineering Mechanics with Marine Applications I (3-2-4).
First course in two-semester sequence covering the principles of engineering mechanics of rigid and deformable bodies for naval architecture students. Topics in the first course include forces, moments, static equilibrium, stress, strain, stress-strain relations and transformations, torsions in shafts, flexure in beams, and temperature effects.

- Demonstrate the ability to use vector mechanics and static equilibrium for the analysis of external and internal forces and moments acting on a simple static rigid structure.
- Demonstrate the ability to compute geometric properties of a composite structural section, including computation of centroid and moment of inertia (2 nd moment of area).
- Demonstrate the ability to use mechanics of materials to find the state of stress within a simple static deformable structure subject to external loads, including application of axial loads, torsional loads, bending and shear loads, and combined loads.
- Demonstrate the ability to use mechanics of materials to relate the state of stress and state of strain within a simple static deformable structure subject to external loads, including application of axial loads, torsional loads, bending and shear loads, and combined loads.
- Demonstrate the ability to use mechanics of materials to determine the state of stress or strain within a simple static deformable structure as a transformation from one orientation of a coordinate system to another orientation, including determination of principle stresses and maximum shear stress at a point.
- Determine the loadings on a structure which would cause failure (Von MIses and Tresca).
