Also, what is the magnitude of the u resultant force? F F F i j k i j k i j k N The magnitude of F is 2 2 2 2 2 2 The positive sign indicates that this component points in the same direction as uAC. The unit vectors u and u of F and F must be determined first. The vertical force F acts downward at on the two-membered frame.

By resolving F1, F2 and F3 into their x, y, and z components, as shown in Figs. Applying the sines law of referring to Fig. Determine the magnitude of hibbelrr resultant force and its y hibbelerr, measured counterclockwise from the positive x axis.

And its coordinate direction angles are F2 x – Determine the angle u between cables AB and AC. Determine the magnitude of the projected component of z the lb force acting along the axis BC of the pipe. If the force in each cable tied to the bin is 70 lb, determine z the magnitude and coordinate direction angles of the resultant force.

The coordinate direction angles of F are 1 1 cos cos Determine the magnitude and direction u of FA so that the y resultant force is directed along the positive x axis and has a magnitude of N. Force F acts on the frame such that its component acting B along member AB is lb, directed from B towards A, and the component acting along member BC is lb, directed from B towards C. Determine the magnitude and coordinate direction angles of F2. Express each of these forces as a Cartesian vector. If the resultant force acting on the support is to be lb, F directed horizontally to the right, determine the force F in A rope A and the corresponding angle solugions.
