is this moments equation correct...
taking moments about P ,
this gives x=2.3m and my book says the answer is
A woman and a man support a non-uniform plank, AB of mass 10kg and length 4m. The woman holds the plank 1m from A and the man holds the plank at B. The vertical reaction provided by the woman is 56N find;
A) the vertical reaction force provided my the man
b) The position at which at which the weight of the plank acts measured from A.
