An architecture student working at a drafting table requires some muscle action in order to support her head. As shown in the figure, three forces act on her head. If theforce provided by muscles is FM = 70 N and the weight of her head is W = 31 N, determine the magnitude and direction of the force provided by the upper vertebrae Fy tohold her head stationary. Assume that this force acts along a line through the center of mass of her head as do the weight and muscle force. (Assume the +x-axis to be tothe right.)magnitudeNdirectionmeasured clockwise from the -x-axisCG4013

The following figure represents a bicep curl maneuver where the center of mass (CoM) of a 23 kg dumbbell is 0.29 m from the elbow joint (pivot). The mass of the arm is 5 kg and acts 0.17 m from the elbow joint, and the biceps tendon acts at a distance of 0.01 m from the elbow joint. What is the required magnitude of the resultant joint reaction force (JRF) at the elbow in newtons (N) for the scenario described above in a) where static equilibrium is achieved.
A meter stick is supported by a knife-edge at the 50-cm mark. You hang masses of 0.40 kg and 0.60 kg from the 20-cm and 80-cm marks, respectively. Where should you hang a third mass of 0.30 kg to keep the stick balanced?
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.
