Question

Note that the angles are the direction cosine from the notes corresponding to α, β, and y. 1. Four forces are applied at a point in a body as shown Determine the F4xN 30 magnitude and direction (angles ee,, and e) of the resultant R of the four orces. i40° 50 40 Three forces are applied with cables to the anchor block shown in Fig. P2-98. Determine (a) The magnitude and direction (angles θ*, ey, and θ-' of the resultant R of the three forces. 0.6 m F, = 272 N F,=500 N F3 650 N 2.7 mi 3.6 m (b) The magnitude of the 1.8ml 2.7 m rectangular component of force F, along the line of action of force F 0.9 m1.2n 3.6 m (c) The angle α between Fig. P2-98 forces F, and F 3
