If the resultant force of the two tugboats is 3kN, directed along the positive x axis , determine the required magnitude of force Fb and its direction θ.

The turnbuckle is tightened until the tension in the cable AB equals 2.4 kN. Determine the vector expression for the tension T as a force acting on member AD. Also find the magnitude of the projection of T along the line AC. 3 m Z D B 5 m 2 m m

The turnbuckle is tightened until the tension in the cable AB equals 2.4 kN. Determine the vector expression for the tension T as a force acting on member AD. Also find the magnitude of the projection of T along the line AC.

The beam is to be hoisted using two chains. If the resultant force is to be 600 N directed along the positive y axis, determine the magnitudes of forces F4 and Fg acting on each chain and the angle 0 of FB so that the magnitude of FB is a minimum. F4 acts at 30° from the y axis, as shown. FB FA 30°

Three chains act on the bracket in such a way as to generate a resultant force of 2224 N. If two of the chains are subjected to known forces (P1 and P2) as shown in the figure, determine the orientation Ѳ of the third chain, measured clockwise, from the positive x axis, so that the magnitude of the force, F, on this chain is minimal. All forces lie in the x - y plane. What is the magnitude of F? TIP: First find the resultant of the two known forces, the force F acts in this direction. Note: P1 = 400 lb and P2 = 300 lb

4. The wrench is subjected to the 200-N force and the force P as shown. If the equivalent of the two forces is a force R at O and a couple expressed as the vector M = 20k N m, determine the vector expressions for P and R. 300 mm 200 N 160 mm Ans. P = 40j N R = -160j N

If FA= 6 kN and FB=3 kN determine the magnitude of the resultant force (A) and specify the location of the resultant force on the x-y plane (B).

The convergent system of 4 forces acting on an absolutely rigid body is balanced (ΣFKY = 0). Determine the projection of the fourth force on the Oy axis if F1y = 160.0 kN; F2y = -46.0 kN; F3y = 36.0 kN;.

The two forces and a couple acting on the beam are equivalent to a single force acting at C. Determine the distance d that locates point C.
