Mechanics Lecture Notes1 Lecture 1: Statics equilibrium of a IntroductionThis Lecture deals with forces acting on a particle which does not move, is inequilibrium. Theimportant concept is the resolution of forces to obtain the equations determining equilibrium. It isessential when solving such problems to start with a good diagram showing all the example introduces the idea of friction which, although simple at first sight, turns out tobe quite subtle. The idea of limiting friction is introduced: this occurs when something is just onthe point of Key concepts Reduction of a number of forces to oneresultantforce by vector addition. Condition for equilibrium: the resultant force is zero. Resolution of forces in orthogonal directions to determine an unkown force. Frictional force;limiting frictionand relation via thecoefficient of frictionto the ForcesWe consider here the the situation of a stationary particle acted on by a number of forces.
Mechanics Lecture Notes 1 Notes for lectures 2 and 3: Equilibrium of a solid body 1.1 Introduction This lecture deals with forces acting on a body at rest. The di®erence between the particle of the last lecture and the body in this lecture is that all the forces on the particle act through the same
