the quiz and in class work The only exception is for University Excused Absences see http student rules tamu edu rule7 htm Proper documentation must be submitted for the absence within one week following an excused absence In accordance with recent changes to Texas A M University Student Rule 7 be aware that in this class a confirmation note from your medical provider is required for any

file on ecampus to make sure you do all the required parts of each assignment No late work is accepted No homework score will be dropped when determining your final average The lowest score for a Quiz will be dropped when determining your final average There will be no make up exams quizzes hw unless you are have an excused absence Concerns or mistakes that may have been made in grading quizzes or exams must be addressed in writing within a week of when the item is returned This will be a so called flip class which measn we will spend approximately 1 3 time on lectures and 2 3 on in class work There will be videos available for further explanations of course material Notice The Americans with disabilities Act ADA is a federal anti discrimination statute that provides comprehensive civil rights protection for persons with disabilities Among other things this legislation requires that all students with disabilities be guaranteed a learning environment that provides for reasonable accommodation of their disabilities If you believe you have a disability requiring an accommodation please contact the Disability Services disability tamu edu in Room B118 of Cain Hall or call 845 1637 Course Learning Outcomes At the end of this course students should be able to 1 Identify isolate and idealize the system of interest for the application process a Decide whether the system is to be thought of as a particle collection of particles or rigid body b Draw a free body diagram of the system showing external forces and moments 2 Identify the nature of the connections between bodies and create an idealized representation for it a Recognize support conditions for idealized connections such as a pin hinge roller etc b Handle non ideal connections and empirical laws 3 Convert the task from the real world into a symbolic representation 4 Develop equilibrium relationships for non accelerating particles acted on by forces 5 Develop equilibrium relationships for non accelerating two or three dimensional rigid bodies a Calculate the direct resultant forces and rotational resultant moments effects of external stimuli on a rigid body 6 Identify the need for additional empirical laws such as Hooke s Law and Coulomb Friction to complete the system of equations 7 Estimate external loads and find the internal forces in frames trusses beams and other structures while evaluating their structural safety a Analyze systems of interconnected rigid bodies b Find the forces generated by the constraints c Find internal shear and bending moments for beams d Analyze systems with non ideal constraints under the action of dry friction 8 Obtain system information position velocity etc at a given location or time knowing the system information at a different location or time a Use Newton s Laws to describe the motion of the system b Choose a suitable coordinate system to work in such as Cartesian polar or path coordinates c Express the position velocity and acceleration in the chosen coordinates 9 Find the loads and accelerations for rigid bodies under planar motion a Calculate centroids and moments of inertia of bodies b Calculate the effect of forces and motion of a rigid body undergoing translation and rotation Contribution of course to requirements of ABET Criterion 5 Subject Semester hrs Subject Semester hrs Mathematics Engineering Science 3 Basic Science Engineering Design Subject General Relationship of course to program outcomes ABET Program Outcome x a ability to apply knowledge of mathematics science and engineering x e ability to identify formulate and solve engineering problems x k ability to use the techniques skills and modern engineering tools necessary for engineering practice Semester hrs Aggie Honor Code An Aggie does not lie cheat or steal or tolerate those who do Upon accepting admission to Texas A M University a student immediately assumes a commitment to uphold the Honor Code to accept responsibility for learning and to follow the philosophy and rules of the Honor System Students will be required to state their commitment on examinations research papers and other academic work Ignorance of the rules does not exclude any member of the Texas A M University community from the requirements or the processes of the Honor System For additional information please visit www tamu edu aggiehonor Policy on Academic Integrity Why it is important Technical competence I want you to be able to perform well technically as an engineer I want each of you to be able to perform well individually Ethical competence I want you to be ethically competent While you may be able to succeed in the short term by being unethical just as you may get good grades by cheating in school long term
