Homework Statement
Determine the x- and y-coordinates of a point through which the resultant of the parallel forces passes.
The Attempt at a Solution
The first thing I did was to find the resultant forces, which is R = 0i + 0j -125 k
Then I found the moment of each axis
so
M = (-65(12) -65(6) +60(12) +35(12) ) i + (-65(11)-35(15)+90(15))j + 0k
M = -30 i + 110 j
Then the next thing I did is
r x R = M
so
(xi + yj + zk) x (-125 k) = (-30 i +110 j)
-125y i + 125x j = -30 i + 110 j
so x and y I got is
x= 0.24
y = 0.88
why is it wrong?
Thanks for the help
