4. Use graphical (parallelogram) method to determine the resultant force R Draw a vector sum diagram (with ruler, protractor, compass) on a graph sheet using scaling factor of 0.5 N/cm, i.e., 2 cm for 1 N. (Note: graphic sheets are provided at the end of Exp 4 lab manual). Measure the magnitude R and the orientation angle 0; of the resultant force Ř. Record the magnitudes (R & E) and orientation angles (@j & 0) in the row “Graphic result" of each Table. 5. Use analytical method to determine the resultant force R. • Using component method (Fig. 3) compute the magnitude R and the orientation angle or of the resultant force R. Record the magnitudes (R & E) and orientation angles (0; & 0) in the row “Analytical result" of each Table. . R Table 1 Results of Measurement #1: F1: 200 g at 60.0°; F2: 200 g at 150.0°.
