Answer #1

70.34 19.66° 6 lb The 6 lb force can be resolved into parallel and perpendicular components based on the triangle sides relationships with the 19.66 angle. The perpendicular component is adjacent to the 19.66 angle, while the parallel component is opposite the 19.66 angle: P Psin 19.66 -б sin 19.660 P 2.02 b And 5.65 lb Thus components of forces is P 2.02 lb and P -5.65 lb

63.66 26.34° 9 lb 38.66 The 9 lb force can be resolved into parallel and perpendicular components based on the triangle sides relationships with the 26.34° angle. The perpendicular component is adjacent to the 26.34° angle, while the parallel component is opposite the 26.34° angle: Qsin 26.34° 9sin 26.34° 2-3.99 1b 0, cos 26.34° Q,-9 cos 26.34° Q,-8.07 Ib Thus components of forces is 0 -3.99 lb and Q, 8.07 lb
