EM 214 STATICS
(3-0) 3 credits. Corequisite: MATH 125. The study of the effects of external forces acting on stationary rigid bodies in equilibrium. Vector algebra is used to study two and three dimensional systems of forces. Trusses, frames and machines, shear and moment in beams, friction, centroids, moments of inertia, and mass moments of inertia are discussed.

EM 215 DYNAMICS
(3-0) 3 credits. Prerequisite: EM 214. Newton’s laws of motion are applied to particles and rigid bodies. Absolute and relative motion; force, mass and acceleration; work and energy; and impulse and momentum.

EM 216 STATICS & DYNAMICS
(4-0) 4 credits. Prerequisite: MATH 125. Statics: the study of effects of external forces acting on stationary rigid bodies in equilibrium. Frames and machines, friction, centroids and moments of inertia of areas and mass are discussed. Dynamics: Newton’s laws of motion are applied T particles and rigid bodies. Topics considered are absolute and relative motion; force, mass, and acceleration (or particles and rigid bodies); work and energy; and impulse and momentum (of particles).

EM 217 STATICS AND MECHANICS OF MATERIALS
(4-0) 4 credits. Prerequisite: MATH 125. Integrated course involving the study of force systems in equilibrium and the mechanics of deformable bodies. Emphasis is placed on the basic concepts of the static behavior of rigid bodies and the behavior of deformable bodies under loadings common to engineering problems.

EM 218 EXPERIMENTAL ANALYSIS OF STRESS AND STRAIN
(0-1) 1 credit. Prerequisite: Preceded by or concurrent with EM 321 or EM 217. Laboratory procedures common to the mechanical design area are studied and developed. Methods and applications of tension and bending tests will be explored. Procedures studied will include topics such as strain rosette analysis, tension, torsion, and bending tests, fatigue, photoelasticity, and brittle coatings.

EM 321 MECHANICS OF MATERIALS
(3-0) 3 credits. Prerequisite: EM 214. Basic concepts of stress and strain that result from axial, transverse, and torsional loads on bodies loaded within the elastic range. Shear and movement equations and diagrams; combined stresses; Mohr’s circle; beam deflections; and column action and equations.

EM 327 APPLIED FLUID MECHANICS
(4-0) 4 credits. Prerequisites: EM 321, EM 217, or permission of instructor. An introduction to the static and dynamic properties of real and ideal fluids; application of continuity, energy, and momentum principles to laminar, turbulent, compressible, and incompressible flows; laminar and turbulent flow of fluids in closed conduits and open channels; flow through orifices, weirs, and venturi meters; and flow in pipe networks and pumping systems.

EM 328 APPLIED FLUID MECHANICS
(3-0) 3 credits. Prerequisites: EM 214 or concurrent enrollment in EM 217, or EM 216. Topics will include an introduction to the static and dynamic properties of real and ideal fluids; application of continuity, energy, and momentum principles to laminar, turbulent, compressible, and incompressible flows; laminar and turbulent flow of fluids in closed conduits and open channels; flow through orifices, weirs, and venturi meters. Flow in pipe networks and pumping systems will be investigated using a projectized team approach.
