Topics 47 Topic 4 Forces Loads and Stresses Types of Forces Internal Tension compression shear torsion bending External Dead Load Permanent force acting on a structure Includes the weight of the structure itself. A force is a . conservative force. if the net work it does on a particle moving around any closed path, from an initial point and then back to that point, is zero. . Equivalently, a force is conservative if the net work it does on a particle moving between two points does not depend on the path taken by the particle. . Here’s Tim & Mobey on Force. Brainpop. Suppose I asked you to move a heavy desk in the classroom. How would you move it? . hmmmmmmmmmmm...... You might get on one side of the desk and start pushing, Or you might grab the legs and start pulling. . Newton’s Laws. Isaac Newton.
