Companion CD contains 8 animations covering fundamental engineering mechanics concept 3. Introduction Equilibrium of Concurrent and Coplanar Force Systems Lami's Theorem Free Body Diagram Examples 2. If three concurrent forces are to be in equilibrium, the sum of two smallest magnitudes must be greater than the magnitude of third force. Concurrent forces All the forces of a system pass through a common point. In 2 dimensions, if all the forces are NOT concurrent then you must have equilibrium both forces and moments. We need to find the angle that force T makes with the positive x-axis first. This is called static concurrent equilibrium. The gusset plate is subjected to the forces of three members. The 7th edition of this classic text continues to provide the same high quality material seen in previous editions. A single force that is equivalent to a given force system is called the resultant of the force system. When this force is added to the force system, the sum of all of the forces is equal to zero. In 2-D, two conditions are need to be stratified for a body to be inn equilibrium: The arithmetic sum of all forces in x-direction or in horizontal direction should be zero. The concepts of torque and moment of inertia will be the focus of this module. If a body is not accelerating is in equilibrium, so resultant of all forces = 0.
