A man exerts a force Fon the handle of the stationary wheelbarrow at A. The weight of the wheelbarrow along with its load of dirt is 185 lb with center of gravity at G. For the configuration shown, what force F must the man apply at A to make the net moment about the tire contact point B equal to zero? Assume a = 38 in., b = 7 in., h = 21 in., 0 = 19°, and o = 56°. F W h |B a Answer: F = i Ib
