New to forum. Learning Phys I on my own distant learning. I get Trans. Equil as sum of all forces = 0 however choices not so simple. Choices are:
1) only if at rest
2) only if moving at constant velocity
3) only if it is either at rest or moving with constant velocity
4) if it is moving with either constant velocity or constant acceleration
boy (unk mass)-----4m--------(fulcrum)----1m-----80kg man
balanced
What is downward force exerted on fulcrum?
1) zero Newtons
2) 100N
3) 600N
4) 800N
5) 1000N
