2/91 Express F as a vector in terms of the unit vectors i, j, and k. Determine the projection, both as a scalar and as a vector, of F onto line OA, which lies in the x-y plane. Answer 2 1 30° A 2 1 | 40° F = −1.843i + 2.63j + 3.83k kN FOA=-0.280 kN FOA = -0.243i - 0.140¹1j kN F = 5 kN 35° PROBLEM 2/91
