Assuming that the system is in equilibrium, find the value of m3, knowing that: * r1 = 1.5 m  *r2 = 0.9 m *r3 = 1.7 m  m1 = 11 kg m2 = 3.1 kg m3 = ?

2. Bones and Muscles. A patient in therapy has a forearm that weighs -20.5Nj and that lifts a -112.0Nj weight. These two forces have direction vertically downward. the only other significant forces on his forearm come from the biceps muscle (which acts perpendicularly to the forearm) and the force at the elbow. If the biceps produces a pull of 232 N when the forearm is raised above 43° the horizontal, find the magnitude and direction of the force that the elbow exerts on the forearm. (The sum of the elbow force and the biceps force must balance the weight of the arm and the weight it is carrying, so their vector sum must be 132.5 N, upward.) Vector addition Given the following vectors: A = 10mi + 20m 2 4. P=Z+L 5. F=A+L+G+L 6.

13. An object weighing 500kg is to be pulled by a man by exerting a force P. Force P is inclined at an angle of 25 deg. measured from the positive axis. The object and the floor has a coefficient of friction: static = 0.35 and dynamic=0.15. What should be the magnitude of P to cause an acceleration to the object equal to 0.51 m/s^2. Express your answer in unit of KN. 15. An object weighing 500kg is to be pulled by a man by exerting a force P. Force Pis inclined at an angle of 25 deg. measured from the positive axis. The object and the floor has a coefficient of friction: static = 0.35 and dynamic = 0.15. From item 5, when the required value of P is applied, what would be the total distance travelled by the object after 10s? Express your answer in unit of m.
