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 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;.

Two cables are used to secure the overhang boom in position and support the 1875 N load. If the resultant force is directed along the boom from point A towards O, determine the values of x and z for the coordinates of point Cand the magnitude of the resultant force. Set Fg = 1685 N (where position of Fg along x axis = -2 m, along y axis = -6 m and along z axis = 3 m) and FC = 2050 N (where position of Fc along y axis = -6 m). Determine the magnitude of the resultant force in kN is (round to two decimal places), and the value of x coordinate of point Cin m (round to two decimal places), and the value 12 mB 3 m 6 m of z coordinate of point Cin m (round to two decimal places).

The boat is to be pulled onto the shore using two ropes. If the resultant force is to be 80 KN, directed along the direction of the boat, determine the magnitudes of forces T and P acting in each rope and the angle θ of P so that the magnitude of P is a minimum. T acts at 30o .

Determine the projected component of the force F=12 lb acting in the direction of the cable AC. Express the result as a cartesian vector.

If the magnitude of the resultant force is to be 9 kN directed along the positive x axis, determine the magnitude of force T acting on the eyebolt and its angle e. 45° 8 kN

The resultant of the three cable tension acts along the y-direction. Determine T1 given that T2 = 980 N.
