Procedure Part 1 - Graphical Method 1. Calculate the scale of each force. In your drawing, have 4 cm of length represent 1 N of force. Input your values into the Data table. 2. Use the head-to-tail method with the appropriate scaling to determine R. Measure and label the magnitude and angle of each individual vector. Draw the resultant vector, R, as a dotted line (or with a different color). 3. Calculate the force of R using the scaling factor 1 N = 4 cm. 4. Measure the angle of the resultant using a protractor. 5. Each force diagram should include the graphical addition of the two or three input forces and the resultant force R. Label all angles (in degrees) and magnitudes (in both cm and N). 6. Starting on a new piece of graph paper each time, repeat for each trial.
