Catalog Description

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, column buckling, and temperature effects.

Goals

  1. 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.
  2. 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).
  3. 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.
  4. 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.
  5. 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.
