correct me if im wrong, but the sum of your forces in the y =/= 0. pushing down we have 3/5 * 100 + 9.81*100 = 1041N however, your forces going up add to 735.3 N I got NA = 362.56 and NB = 678.44

Yeah, that makes more sense than mine

[@michaelyiu3303]

So the answer here is wrong since Na +Nb=\= 1041?

So I think the answers were divided by two because there are two wheels on the front and two on the back. So each wheel feels that N.
