Homework Statement
A uniform plank is supported by two equal 120 N forces at X and Y. The support at X is then moved to Z (halfway to the plank center).
The supporting force at Y then becomes?
_____________________________
X...Z...c......Y
i tried to draw it above. The line is the plank, X and Y are the supports, Z is where X is moved to, and (c) is the center of the plank
The Attempt at a Solution
I came across this as i am studying for my test and i am a little lost.
The solution says to do this:
(240 N)(1/4L) = Fy(3/4L)
and the answer is 80 N
I am confused on where this solution comes from.
Any explaining would be very helpful :)
Thank you
