I would first find the coordinate of B using the lengths given
DanJS
  • DanJS
looks like you have to play around and find some lengths the hinge is (0,0,0,)

@DanJS That's the part where I'm struggling. I'm trying to use the 45degree angle

I see. So then after getting the required lengths. we use the formula A = Axi + Ayj + Azk?
dan815
  • dan815
where x,y,z are the compnents of the unit vector it has to be a unit vector in the direction u want
dan815
  • dan815
so that the magnitude of (k*unitvector) = k where k is 500 in this case,

  • dan815
this is a way to see how to divide your 500 Newtons of force into its component form

After u get the start and end points of the vector, use V =<(x2-x1) , (y2-y1), (z2-z1)> The unit vector length 1 in the direction of V is , the V over its magnitude Then multiply that by the force at A, to get the force vector, as dan did

the v roof hat, is the unit vector of length 1
