The traffic light shown in Figure is supported by a system of cables. Points A and B are in a vertical plane which is parallel to x-z plane. Point C is in y-z plane. The traffic light has a mass of 75 kg. Determine the following: (a). Position vectors for OA, OB and OC (b). Write equilibrium equations in the x, y and z directions (c). Find the tensions in cables OA, OB and OC (show all your workings that you do to find these) Image is at http://www.imagesup.net/?di=3135702364213
Question has been answered here: http://www.chegg.com/homework-help/questions-and-answers/the-access-door-is-held-in-the-200-open-position-by-the-cable-ab-as-shown-in-figure-5-the--q3496608 , but there is no explination or workings about how the answer for question a) was found? Also the image posted is very hard to read....

(x) OA =(x-x)x -(x-x)x +(x-x)x = xx -8j +xx

xx = xx +5k

xxxxxxx in xxxxx x =xx*(xx +5k)/89

y xxxxxxxxx xx xxxxxxx = -xxx/xxx -8Tb/105 +xxx/xx

total xxxxx in x xxxxxxxxx = x xxxxxxxx of xxxxxxx = xxx/xxx +6Tb/105

total xxxxx xx z direction = z xxxxxxxxx xx xxxxxxx + xxxxxx of xxxxxx xxxxx

hence -xxx/xxx -xxx/xxx +xxx/xx= 0

xx Tc = xxxxx/xxx

hence xxx/xxx +xxx/xxx +xxx/xx -75g =x

-x.xxx/xxx +xxx/xxx +xxxx/xxx-xxx = x

xx.xxx = 75g105
