9) If C1 = - 3 cm/s, the force F needed to pull the wire is 452 dyne. IV. The force components Rx and Ry of the air acting on the deflecting blade are desired. The vane is fixed and the air velocity is 30 ft/s. Air density is 0.078 lb/ft3. 10) Rx = 0.08875 lbf. 11) Ry = 0.02378 lbf. If the vane moves to the left at 10 ft/s, 12) Rx = 0.1578 lbf ................
