ChE Tulsa University

ES 2013 Statics
Required course for ChE

Catalog Description:  Statics of particles and rigid bodies, equilibrium of rigid bodies, distributed forces, centroids, forces in beams and cables, friction, and moments of inertia. 

Prerequisite:  Physics 2053

Textbook:  Vector Mechanics for Engineers, Statics, 7th Edition, Ferdinand P. Beer, E. Russell Johnston, Jr., and Elliot R. Eisenberg, McGraw-Hill , NY, 2004.

Reference:  Classroom Handouts, Powerpoint slides.

Course Objectives:  The main course objective is:  To broaden the student’s understanding and application of principles of vector mechanics introduced in physics, expand equilibrium to include internal forces in members and develop an understanding of centroids and moments of intertia.

Major Topics Covered in the Course:

Statics of Particles:  forces in a plane, vector notation and addition, equilibrium of a particle, Newton’s first law of motion, forces in space – rectangular components of a force in space, line of action, addition of concurrent forces in space, equilibrium of a particle in space.

Rigid Bodies – equivalent systems of forces, external and internal forces; transmissibility; equivalent forces, vector products, moment of a force about a point, Varignon’s Theorem, moment vectors/couples, equivalent and equipollent systems, reduction of a system of forces.

Equilibrium of Rigid Bodies – free body diagrams, equilibrium in two and three dimensions, supports, connections, statically indeterminate, partial constraints and reactions.

Distributed Forces – centroids and centers of gravity (areas, lines, and volumes).

Analysis of Structures – simple trusses (method of joints and sections), frames and machines, multiforce members.

Forces in beams – internal forces in members, determination of shear and bending moment equations and their diagrams.

Friction – laws of dry friction, angles of friction, wedges and belt friction.

Distributed Forces (moments of inertia) – area moments of inertia, (integration and composite areas), polar moment of inertia, radius of gyration of an area, parallel-axis theorem, mass moments of inertia, thin plates, three dimensions, composite bodies.

Class/laboratory Schedule:  Class meets twice weekly for 75 minutes, lectures in classroom.

Professional Component Contribution:  This course provides 3 hours of engineering science.

Relationship to Program Outcomes:

• Outcome a:  Most of the class is based around Newton’s first and third law.  Virtually all problems require algebra, trigonometry or calculus to obtain a solution.
• Outcome e:  Engineering problems are given and the students must choose a solution method, create a free body diagram and solve the problem.
