Three forces are applied to a body. They are :
F1 = (4,5) applied at (1,2)
F2 = (2,-1) applied at (3,-1)
F3 = (-3, 2) applied at (-2,1)
i) Find the resultant force
Answer : R = (3,6)
ii) Find the total moment about the origin
(This i know how to do)
iii) The line of action of R cuts the Y-axis at (0,d). Find d
iv) Find the equation of this line of action
How do I solve these last two questions??!!
Thank you for any help
