EN222: Engineering Mechanics with Marine Applications I

Catalog Description

EN222 Engineering Mechanics with Marine Applications II (3-2-4).

The second course in a two semester sequence covering the principles of engineering mechanics of rigid and deformable bodies for naval architecture students. Topics in the second course include: generalized Hooke's Law and states of stress, structural failure theories, motion of a point, energy methods, impact loadings, momentum methods, planar kinematics of rigid bodies, energy and momentum in rigid body dynamics and single DOF vibration analysis.

Class notes and laboratory handouts


  1. Understand and be able to use elastic beam analysis methods to find the stresses and deflections in a beam under a variety of loading conditions.
  2. Understand and be able to use column theory to determine loading capacity of column with different geometries and end conditions.
  3. Be able to construct free body force diagrams and kinetic diagrams for particle or rigid body motion, understand the relationship between them and use them to formulate equations of motion.
  4. Be able to formulate work-energy relationships and use them to solve problems involving particles and rigid bodies.
  5. Be able to find the equation of motion for single DOF oscillators and solve for motion amplitude, velocity, acceleration and phase.
  6. Be able to develop a spreadsheet program to solve typical problems in engineering mechanics and to clearly present the solution.
