A person in carrying a weight of W by hanging it from one end of a bar with length l and placing the bar on his shoulder. The person is maintaining the equilibrium by applying a force on the opposite end of the bar by his hand. Assume that the distance between his hand and shoulder is y. Which of the folowing values of y will produce the minimum force on hos shoulder ?

A \( y = \frac{1}{2} \)

B y=l

C \( y = \frac{3}{4} l \)
