1) see pdf
for question 2 I'm unsure how to calculate the force at the fulcrum since its not in equilibrium. I thought maybe i would add the two forces together, but that doesn't seem right.
2) so this question asks for what forces need to be applied at points A and B and i understand what forces need to be applied at A ( i think ). but at point B wouldn't the fulcrum have to have an equal amount of force pushing up...so 50+20 = 70N...doesn't seem right since the fulcrum isn't centered.
please see pdf attached, thanks in advance
