determine the resultant of the system of force having the following magnitude and passing through the origin and the indicated point  p = 280 lb (+10, +6, +4)  T = 520 (-3, -4, +10) F = 270 (+5, -3, -6)

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

Determine the magnitude of the resultant force FR = F1 + F2 and its direction, measured counterclockwise from the positive x axis. F = 250 lb -30 F; = 375 lb

If P1 = 50 kN , P2 =100 kN and C = 120 kN-m, determine the resultant of the system.

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 .

Resolve the 360-N force into components along the cables AB and AC. Use α = 55° and β= 30°.

The 60-N force acts on the end of the pipe at B. Determine the angles Ø (0° ≤ Ø ≤ 180°) of the force that will produce maximum and minimum moments about point A. What are the magnitudes of these moments?Note: Change the 0.7m dimension into 0.8m

•2-9. The plate is subjected to the two forces at A and B as shown. If 0 = 60°, determine the magnitude of the FA = 8 kN resultant of these two forces and its direction measured clockwise from the horizontal. A 40° FB = 6 kN

Find the components of the force F =(14i-5j+2k)N acting in the direction of the vector a = 4i-3k. Hence, express as vectors the parallel and perpendicular components of F relative to a
