ENES 102 Statics
Welcome
ENES 102 Statics 3 credits
Introduction to statics of particles, rigid bodies, forces, moment and equilibrium
equations of rigid bodies. Distributed forces, centroids, and center of gravity. Analysis
of structures, forces in cables, friction moments of inertia. PREREQUISITE: MATH 181
with a grade of C or better.
Three hours lecture each week.
Course Outcomes
Upon course completion, a student will be able to:
- Apply principle of mechanics, idealization and do unit conversion.
- Add and resolve forces in 2D and 3D space, calculate force vectors either in terms of Cartesian components or magnitude/direction.
- Compute moment about an axis in 2D and 3D and to reduce a simple distributed loading to a resultant force having a specified location.
- Draw a free-body diagram of a rigid body and write and solve the equations of the equilibrium of the rigid body.
- Apply equilibrium concept/techniques to solve simple 2D structural problems and use method of joint and method of section to truss structure.
- Identify the internal forces in a member of structure and draw shear-moment diagrams of a beam.
- Know the concept of the friction and how to manipulate the friction force.
- Comprehend the concept of centroid and determine its location for a discrete system and a continues body of arbitrary shape in 2D.
- Define the moment of inertia of for area for a simple area in 2D.
