The weight acts at the middle of the bar. See Figure. Taking moment about the ground we find F1 = W/2

Q. A heavy iron bar of weight W is having its one end on the ground and the other on the shoulder of a man. The rod makes an angle $θ$ with the horizontal, the weight experienced by the man is

W cos $θ$

W sin $θ$

W $θ$

$W /2$
