Lecture 5 Equilibrium
Static deals primarily with the description of the force conditions necessary and sufficient to maintain the equilibrium of engineering structures. When body is equilibrium, the resultant of all forces acting on it is zero. Thus, the
Engineering mechanics "Static"
Before dealing with a group or system of forces, it is necessary to examine the properties of a single force in some detail, A force has been define as an action of one body on another. In dynamics we
Lecture 6 Friction
Tangential forces generated between contacting surfaces are called friction forces and occur to some degree in the interaction between all real surfaces. whenever a tendency exists for one contacting surface to slide along another surfa
