Find the Magnitude and Direction of the Resultant of the Three

question 76

Short Answer

Find the magnitude and direction of the resultant of the three force vectors, A\overrightarrow { \mathrm { A } } , B\overrightarrow { \mathrm { B } } , and C\overrightarrow { \mathrm { C } } , shown in the figure. These vectors have the following magnitudes: A = 5.0 lb, B = 7.9 lb, and C = 8.0 lb. Express the direction of the resultant by specifying the angle it makes with the +x-axis, with counterclockwise angles taken to be positive.
