 Lecture 1 Play Video The Triangle Rule Adding Vectors to find a ResultantThis video covers triangles, the triangle rule, Law of Cosines and Sines. Lecture 2 Play Video 2D Find Resultant Vectors, Triangle Rule, Cartesian ComponentsThis will teach you about 2D resultant vectors, the triangle rule, and cartesian components. Lecture 3 Play Video Resolving a 3D Vector into Cartesian ComponentsThis is a statics lesson to derive angle phi and angle theta z. These equations are used when a vector is given by two angles but needs to be resolved into xyz components. Lecture 4 Play Video 3D Statics about a Particle Calculating unit VectorsThis will teach you how to solve 3D statics about a Particle, and how to calculate unit vectors. Lecture 5 Play Video 2D Statics about a point, calculating tension in cables.This will teach you how to solve 3D static problems about a point, and for tension in cables. Lecture 6 Play Video 2D Statics about a particle. Solve for tension in cables.This is a classic 2D Statics problem involving finding the tension in two cables. Lecture 7 Play Video Statics 3D Moment about a point and rXF SolutionThis video contains an example of 3D moment problem utilizing rXF. Lecture 8 Play Video Trusses, Method of SectionsThis will show you how to solve truss problems with the method of sections. Lecture 9 Play Video Truss Method of JointsThis is a brief lecture on solving a truss problem using the method of joints. See my other videos. Lecture 10 Play Video Equivalent Systems, System SimplificationThis is a brief lecture showing you how to solve equivalent systems Lecture 11 Play Video System Equilibrium, 2D Reactions at the SupportsThis video will teach you how to solve System Equilibrium, and 2D Reactions at the Supports. Lecture 12 Play Video Centroid using Composite Shapes, Center of AreaThis method will allow the viewer to find the centroid of an area. I demonstrate the table method to find X bar and y bar. This method also works for finding the center of mass, volume, weight, area, length, etc. Lecture 13 Play Video Centroid Theorem of Pappus Guldinus Volume and Surface AreaThis is how to use Centroid Theorem of Pappus Guldinus to find Volume and Surface Area. Lecture 14 Play Video Shear Moment Diagram, The Equation MethodThis will show you how to draw a Shear Moment Diagram suing The Equation Method. Lecture 15 Play Video Shear Moment Diagram, Graphic MethodThis video shows you how to construct a shear moment diagram using the graphic method. Lecture 16 Play Video Centroid by Calculus, Center of Area using IntegralsThis is the method to use to find a centroid of shapes that are not listed on the table in the back of your Statics book. This is how centroid so far all shapes were originally derived.
