2/36 A man exerts a force F on 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? W 60° 20 26" B -8" 37" PROBLEM 2/36

A man exerts a force F on the handle of the stationary wheelbarrow at A. The weight of the wheelbarrow along with its load of dirt is 200 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 zero? Express your answer in units of lb. 60° 26" F ***** A 20° 37" W G 8"- B

Calculate the moment Mg of the 895-N force about the bolt at B. Simplify your work by first replacing the force by its equivalent force- couple system at A. The moment is positive if counterclockwise, negative if clockwise. Assume F = 895 N, r= 155 mm, h = 490 mm, 0 = 30% = 38° OC Answer: Mg = i 0 h N-m

The motor lifts the 40-kg  crate with an acceleration of 6 m/s2 as shown in (Figure 1). Part A: Determine the x and y components of force reaction at the fixed support A using scalar notation. Express your answers in newtons to three significant figures separated by a comma.   Part B:  Determine the couple moment at the fixed support A. Express your answer in kilonewton meters to three significant figures. Enter positive value if the moment is counterclockwise and negative value if the moment is clockwise.
