ENGR 100 Lecture Notes - Lecture 3: Statics
Document Summary
Inertia: it is the inherent property of a body by virtue of which it can retain its state of rest or uniform motion unless compelled by an external agency. Force: it is an external agency, which overcomes or tends to overcome the inertia of a body. Elements of a force: there are four elements: Newton"s ii law of motion: the rate of change of moment of a body is directly proportional to the magnitude of the force applied and takes place in the direction of the force applied . Statics: statics deals with the action of forces on bodies at rest or in equilibrium. Dynamics: dynamics deals with the action of forces on bodies in motion. Kinematics: it deals with the study of geometry of motion without considering the cause of motion. Kinetics: kinetics deals with a study of motion considering the course of motion. Rigid body: the concept of rigid body is purely theoretical or imaginary.
