Unformatted text preview: Chapter 5 : Applying Newtons Law 1. Using Newtons 1st Law : Particles in Equilibrium Until Chapter 9, we treat an object as a point particle: Rotational motion is not taken into account. Particle in equilibrium F = r x F = y F = One dimensional equilibrium. Consider an athlete hanging on a massless rope Two dimensional equilibrium An inclined plane Tension over a frictionless pulley 2. Using Newtons 2nd Law: Dynamics of Particles Dynamics : the relationship of motion to the forces that cause it F ma = r r x x F ma = y y F ma = : Newtons 2nd Law, vector form : Newtons 2nd Law, component form Dynaics : Problem Solving Strategy 1. Draw a free body diagram. In doing so, identify all the forces. 2. Guess the direction of an acceleration. 3. Choose a coordinate system. 4. Set up equations using Newtons 2 nd Law: F x =ma x , F y =ma y 5. Solve for unknown parameter(s) Beware incorrect free-body diagram Example 5.8) An elevator has a total mass of 800 kg....
