The board sandwiched between two other boards in Figure P4.91 weighs 95.5 N. If the coefficient of friction between the boards is 0.663, what must be the magnitude of the compression forces (assumed to be horizontal) acting on both sides of the center board to keep it from slipping? Figure P4.91
To get up on the roof, a person (mass 70.0 kg) places 6.00-m aluminum ladder (mass 10.0 kg) against the house on a concrete pad with the base of ladder 2.00 m from the house. The ladder rests against a plastic rain gutter, which we can assume to frictionless. The center of ladder is 2.00 m from the bottom. The person is standing 3.00 m from the bottom. Find the normal reaction and friction forces on the ladder at its base.

The center of mass of the arm shown in the figure is at point A. Find the magnitudes (in N) of the tension force Ft and the force Fs which hold the arm in equilibrium. (Let θ = 22.0°.) Assume the weight of the arm is 42.9 N.
Consider a method for measuring the mass of a person’s arm in anatomical studies. The subject lies on her back, extends her relaxed arm to the side and two scales are placed below the arm. One is placed under the elbow and the other under the back of her hand. Construct a problem in which you calculate the mass of the arm and find its center of mass based on the scale readings and the distances of the scales from the shoulder joint. You must include a free body diagram of the arm to direct the analysis. Consider changing the position of the scale under the hand to provide more information, if needed. You may wish to consult references to obtain reasonable mass values.

*60. ao A rigid massless rod is rotated about one end in a horizontal cir- cle. There is a particle of mass m, attached to the center of the rod and a particle of mass m, attached to the outer end of the rod. The inner section of the rod sustains a tension that is three times as great as the tension that the outer section sustains. Find the ratio m,/m2.
Chapter 12, Problem 031 In the figure, a nonuniform bar is suspended at rest in a horizontal position by two massless cords as shown in the figure here. One cord makes the angle 0 40.8 with the vertical; the other makes the angle p 49.2° with the vertical. If the length L of the bar is 2.0 m, compute the distance x from the left end of the bar to its center of mass com Use correct number of significant digits; the tolerance is +/-2%
