The man pulls on the rope at C with a force of 80 lb which causes the forces FA and FC at B to have this same magnitude. What is the magnitude of the resulting force at B? What are the three coordinate direction angles?

2-29. Three chains act on the bracket such that they create a resultant force having a magnitude of 500 lb. If two of the chains are subjected to known forces, as shown, determine the orientation e of the third chain, measured clockwise from the positive x axis, so that the magnitude of force F in this chain is a minimum. All forces lie in the x-y plane. What is the magnitude of F? Hint: First find the resultant of the two known forces. Force F acts in this direction. 300 Ib 30° 200 tb

The Force F acts at the end of the bracket as shown in the diagram. Calculate the moment of the force about point P. P 0.4 m 1 0.2 m 30° F = 400 N

Handle forces F1 and F2 are applied to the electric drill. Replace this force system by an equivalent resultant force and couple moment acting at point O. Express the results in Cartesian vector from. Determine the resultant force and the moment of the resultant forse about the point O. Express your answer in terms of the unit vectors i, j and k.

Determine the magnitude of the resultant force in N of a coplanar force . The horizontal force P=231N and the couple M=501Nm

find the sum of the moments of the Forces in kN.m about Point O, (positive in the counter- clockwise direction). F1 = 60 kN and F2 = 22 kN. 15 m 9 m F1 kN F2 KN

Replace the effect of the forces, with the resultant Fv and the moment M at point D, if the force F1 acts at point A, A = (1,5; 1,5; 2) B= (1; 3,5; 1) F2 at point B and F3 at point C. C=(-1; 5,5; 0) D= (1; 1,5: - 0,5) F = (100; - 20; 0)N F, =(-40; -30; 15)N F, (0;-80; 120)N C YA F, ATA B.
