Q: find the magnitudes of each force Q: Find the direction 0 of each force relative to the positive x-axis 3. Given R= A+B where Vector A has a magnitude of 12 kN pointing 5 from the x-axis, and Vector B has a magnitude of 9 N pointing 115 from the x-axis. Q: Use or sketch the parallelogram rule to show R = A + B Q: Use trig methods to calculate the magnitude of R and the angle in the parallelogram Q: Use or sketch the triangle rule (ie head-to-tail) to show vector R= A + B Q: Express A and B in unit-vector notations Q: Express R in unit-vector notation Q: Find the magnitude and direction of R with respect to the positive x-axis 4. In the diagram below a F is 96 lbs and angle Oa = 130 and 0% = 130. Q: Use or sketch parallelogram rule to resolve the vector F in the a and b directions such that F.+Fb=F. Q: Use trig methods to determine the magnitude of the components of Fie F. and Fo
