Read through the theory and examples regarding the solution of problems to find forces in cables while suspending bodies in equilibrium. 2. Read the textbook explanation regarding the importance of the three internal loads of a member; shear force, bending moment and normal force. 3. Read through chapter 10 in the text; the theory and procedure for determining the moment of inertia by integration. Writing, Problem Solving or Performance 1. Complete a homework problem set from the textbook on the principles of bodies subject to forces that are in equilibrium. Create a free body diagram to declare and analyze the system (this is the model). Perform mathematical analysis to accompany the model created above and solve the system. 2. Given a body with several known forces and two unknown forces, create and use a vector diagram to solve for the unknown forces.
