Question

we know:
|A|=64.7686 , A=(x2-x1,y2-y1), Theta=135 degree
|B|=50
|C|=80
vector directions B and C are unknown but all vector magnitudes are known.
also we know vector A components, and angle , if solution A+B+C=0,
how ve calculate components of A , B and angles.
Thank You Very Much.

Answer 1

consider the circles
A: x^2+y^2 = 64.7686^2
B: (x+45.8)^2 + (y-45.8)^2 = 50^2
C: x^2+y^2 = 80^2
A+B lies on the intersection of circles B and C
so C = -8.87i + 79.51j
and B = C-A = (-8.87+45.8)i + (79.51-45.8) = 36.93i + 33.71i
You can figure the angles of B and C, I assume: tanθ = y/x

Answer 2

Thank you for quick response.
Yes, This is solution.I understand.Thanks again.
But, please download for "Kinematic analysis and synthesis of four-bar mechanisms for strai.pdf"
(here i write the link, but not allowed)
my question is at page 30, eq5.3 and 5.4
what is there (Cu X k) , how we find k?
what is the eq 5.1 and 5.2?
i would prefer a visual basic code for these two equations if possible.

Answer 3

No needs, Thanks.
