COLLEGE OF ENGINEERING AND ARCHITECTURE UNIVERSITY OF THE CORDILLERAS MECH 1 STATICS OF RIGID BODIES MODULE 1: CONCURRENT FORCES ON A PLANE UNIT 1:PRINCIPLES OF STATICS Prepared by: Brian Jhay Guzman, CE, RMP, ME-1 UNIT LEARNING OUTCOMES In this unit, here are the following desired learning outcomes: ✘ Define statics of rigid bodies. ✘ Understand the principle of transmissibility. ✘ Identify the different types of force systems. 2 Introduction to Mechanics Statics Rigid Body Statics is the branch of mechanics concerned with the analysis of loads (force, torque/moment) on physical systems in static equilibrium, that is, in a state where the relative positions of subsystems do not vary over time, or where components and structures are at a constant velocity. When in static equilibrium, the system is either at rest, or its center of mass moves at constant velocity. A rigid body may be defined as a body in which the relative positions of any two particles do not change under the action of forces. Nobody is perfectly rigid. A body when subjected to external forces, it must undergo some form of deformation, however small it may be. 3 Introduction to Mechanics Force It is the agent which changes or tends to change the state of rest or motion of a body. The force is a vector quantity. The characteristics of force are magnitude, direction and point of application. The unit of force is ‘N’, ‘KN’, ‘lbs’, ‘kips’ etc. F= 10 kN Principle of Transmissi ...
