In the case of a front end collision, the a-arm links of a race car will experience tension/compression forces as depicted in the free body diagram (FBD). F = 1000 lbs FBD: F a) Write all three vectors in standard vector notation if 0 = 60 (i.e., in terms of unit vectors i and j). (10 points) b) If the force of the impact is 1000 lbs, determine the forces in the arms F, and F, if Fi + F2 + F = 0 (10 points) Total Points: 20 5. An electric circuit consists of the components shown in the figure below, where Z - R. Zz - R2 + jol and Z, - R; + - joc a) Given R, = 25 02. R. = 15 02, R. = 100 92. Z = 318 mH/C = 531 HE and @ = 20nt rad/s, write Z, Z, and Z, as complex numbers in both their rectangular and polar forms. Show all work. (6 points) b) Suppose Z1 = 25 + j0, Zz = 75 + j20, and Z, = 100 - j30, all measured in 2. Determine the Z2 + Z 3 total impedance Z - Z, + 24. Show all steps. (10 points) c) Suppose Zz = 10+ j10 2 . Write down the complex conjugate Z, & and calculate VZ, . Zz *. (4 points) Total Points: 20
