1. The problem statement, all variables and given/known data A man holds a 6-kg uniform plank. Determine forces at A and B. A is at 1 end of the board and B is 0.6 metres further down. total lenght is 1.4 m 2. Relevant equations w=mg M=fd 3. The attempt at a solution there will be a force down at A and up at B. i think A will just be weight. So 58.9 N not sure about B though.
