2_3_e

Determine the angle  between the edges of the sheet-metal bracket.

2_3_d

A force of F = {-40k} lb acts at the end of the pipe. Determine the magnitudes of the components F1 and F2 which are directed along the pipe’s axis and perpendicular to it.

2_3_c

Determine the angle  between the two cords

2_3_b

Determine the magnitude of the projected component of r1 along r2, and the projection of r2 along r1.

2_3_a

Cable BC exerts a force of F = 28 N on the top of the flagpole. Determine the projection of this force along the z-axis of the pole.

2_2_c

 Determine the position (x, y, 0) for fixing cable BA so that the resultant of the forces exerted on the pole is directed along its axis, from B toward O and has a magnitude of 1 kN. Also, what is the magnitude of force F3?

2_2_b2

Determine the lengths of cords ACB and CO. The knot at C is located midway between A and B.

2_2_a

Determine the length of the connecting rod AB by first formulating a Cartesian position vector from A to B and then determining its magnitude
