THATS RIGHT GIVE ME A KISS HAHAHAbacon_its_bacon said:yeah factor of safety and materials were on the right track.
To Norry: It was definitely 100kg because the bending moment was 750nm at 1.5m (you may have thought it was 3m) as 750/1.5=500N therefore the Reaction A was 500N. then you repeat the process with the other side and get 500N also. Then you test using the bending moments at different points e.g at Reaction B it should be 0 (shown on graph) 500*3 -750*1.5 = 0. This works and therefore the total mass in the middle was 1000N and therefore 102kg
*edit* I hope that made sense. anyone that does engineering should have got the gist of what I was saying.
