- What does static equallibrium mean in mechanics for an object which can move in a two dimensional space? Select all that apply. 1. The object is moving. 2. The object is not moving. 3. Assume that x and y directions are perpendicular to each other. The sum of all the forces on the object is zero in the x direction, but not in the y direction. 4. The sum of all the forces on the object is zero in the y direction, but not in the x direction. 5. The sum of all the forces on the object is zero in both the x and y directions, but not necessarily in all other directions.4. In the diagram at the right, a 12-kg mass is acted on by two forces. Fi is the applied force and acts to a= 7.5 15.5 0=0.6'mls the right. Fz is the frictional force and acts to the left.
