2/40 A man exerts a force F on the handle of the station- ary wheelbarrow at A. The mass of the wheelbar- row along with its load of dirt is 85 kg with center of mass 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?

What do you understand by the term, the robotics?

Representative Problems 2/34 An overhead view of a door is shown. If the com- pressive force F acting in the coupler arm of the hy- draulic door closer is 17 lb with the orientation shown, determine the moment of this force about the hinge axis 0. F-17 Ib PROBLEM 2/34

An experimental device imparts a force of magnitude F = 57 lb to the front edge of the rim at A to simulate the effect of a slam dunk. Compute the moment of the force F about point O and about point B. The moments are positive if counterclockwise, negative if clockwise. Finally, locate a point Ċ from the base at O to the location on the ground where the force imparts zero moment. The distance d from point O to point Ċ is positive if C is to the right of O, and negative if to the left. Assume a = 36 in., b = 28 in., h = 12 in., H = 10 ft, c = 5, and d = 6.
