Unformatted text preview: Horizontal(components) Horizontal(equations) Incline(components) Incline(equations) 5 steps to problem solving 1. What is being asked for ? 2. What is given ? 3. What facts (formula) relate what is asked with what is given. MAKE SKETCH ! 4. Substitute 5. Calculate – CHECK THE ANSWER ! – Does it answer the question ? – Does it make sense ? – Is there a need for rounding ? Methods of problem solving – For 3 forces – sketch a freebody diagram – draw a force triangle – use trigonometry – if right triangle – sin, cos, tan – if not – law of sines – law of cosines – OR Create a scale drawing Methods of Problem solving – More than 3 forces – sketch a free body diagram – break forces into components if necessary – write equations for Σ F x = 0 and Σ F y = 0 – include friction if needed F = μ N...
