given the following system:

2 cords are attached to point C,

and knowing that

|T

|T

find:

1) the moment relative to x,y,z

2) the moment relative to the axis 'OB'

for the 1st part, what i did was

M=M

and i found that

M

M

now comes the problem, how do i find the momentum relative to OB, i know that i need to make a new axis system, where OB is my "y" axis, and an axis 90degrees to it(63.43° from z axis) will be my new "z" axis, while x will stay the same,

i found the angle of my new axis relative to the original system

α=angle between 'y' and OB

α=26.565°

to find the moment, i need

1) force T

2) the shortest distance d

3) force T

4) the shortest distance d

i am not at all sure that this is correct, if you can see a better way let me know.
