31. When determining whether a rigid body is in equilibrium, the vector sum of the gravitational forces acting on the individual particles of the body can always be replaced by a single force acting at: a. a point on the boundary c. the center of mass b. the geometrical center d. the center of gravity 32. If the value of moment arm is zero, the torque produced will be: b. doubled a. zero c. decreased d. can't be determined 33. A meter stick is supported on a fulcrum at the 25-cm mark. A 0.50-kg object is hung from the zero end of the meter stick, and the stick is balanced horizontally. The mass of the meter stick is a. 0.25 kg b. 0.50 kg c.0.75 kg d. 1.0 kg 34. Starting in the spring, fruit begins to grow on the outer end of a branch on a pear tree. As the fruit grows, does the center of gravity of the pear-growing branch a. move toward the pears at the end of the branch b. move away from the pears c. not move at all d. impossible to determine 35. The figure below shows a woman struggling to keep a stack of boxes balanced on a dolly. The woman's left foot is on the axle of the dolly. Assuming that the boxes are identical, which one creates the greatest torque with respect to the axle? The box at the topmost
