Question #1: A rigid body is acted upon by the five forces (Newtons) listed below. The position vectors listed are radii (meters) from the origin of a Cartesian coordinate system to the point of contact of each force on body B. (a) What is the sum of the forces and moments on the rigid body? (b) Explain why the rigid body is not in static equilibrium. (c) Suppose you could apply two additional forces to the rigid body, one force (F1) acting at point (1,0,0) meters and the other force (F2) acting at (4,0,0) meters. Suppose these two forces could put the rigid body into static equilibrium. What are the vector expressions for F1 and F2? force 1: 2i + 3j - 5k, position vector to point of application1: -i + j force 2: 7i - 2k, position vector to point of application2: j - k • force 3: 7i - 2k, position vector to point of application3: i - j • force 4: -i - 3j + 5k, position vector to point of application4: i - k • force 5: -14i + 4k, position vector to point of application5: 2j - k
