CIV100H1 Lecture Notes - Lecture 14: Free Body Diagram, Parallel Rulers
Document Summary
Civ100 - lecture oct 14 equilibrium in 3d. Constraints in 3d and 2d diagrams these need to be on fbd. A member or object in contact with a rough surface. Roller that supports ground pushing back to the wheels. Pin (for 2d) or ball (for 3d) and socket joint. Fx and fy as components at that force in a pin. Fx and fy and a moment about in the x axis mz. Meaning, there is one normal force and one tangential force present. Sometimes, when the roller is restrained from moving sideways, there is a lateral force present. This means that the object can rotate in any direction. So, fx , fy and fz forces are components to our reaction for in the ball. Not being able to rotate results in many actions occurring at the same time. Key equations used in solving equilibrium in 3d.
