Question

Determine the resultant force direction, measured counterclockwise from positive x axis.

Part A If0-60 and F 470 N, determine the magnitude of the resultant force. (Figure 1) FR 496 N Correct Part B ure 1of 1 > Determine the resultant force direction, measured counterclockwise from the positive r axis wer using three significant figures 147 700 N X Incorrect; Try Again Not quite. Check through your wrong number of significant figures.

Answer 1

Tan alpha = F sin theta_1/F_1 + F cos theta_1 thera_1 - Angle between F and F_1 = 135 degrees therefore Tan alpha = 470 sin 135 degrees/700 + 470 cos 135 degrees = 332.3401872/867.6598128 = 0.903933951 therefore alpha = Tan^-1(0.903933951_ = 42.1114989 therefore theta_2 = 195 - 42.1114989 = 152.888 degrees therefore theta_2 = 153 degrees
