moment problem plz help
a small boat hangs from two davits one of which is shown in the figure. the tension in line ABAD is 369 N. Determine the moent about C of the resultant force Ra exerted on the davit at A
ok so first i took the 369N and multiplyed it by the unit vector
(2.4i3.1j1.2k)/(2.4^+3.1^2+1.2^2)^.5 and got (216,279,108)
ok then i took the cross product of (216,279,108) and (2.4,0,0)when i did this i got (0,259.2,670)but the i component shouldnt be zero please help
