sam makes a punch hole with the perforater( two holes ). She presses the lever at A down with a force of 40 N. Calculate the total force which a single pin presses on the paper. 2. Relevant data http://s6.postimg.org/yx62wbild/image.png 3. The attempt at a solution would it be : 40 N X 5 cm = 1,1cm X 'x' ?

we look for f such that 40*(5+1.1)=(2f)*1.1 thus f=... N.
