119. The features of an object or situation that is in static equilibrium are

1. The net force is vertical
2. The velocity is constant
3. The normal forces are all zero
4. The forces sum to zero X
5. The velocity is zero
6. The shear forces are all zero

120. What is true when we compare shear and normal forces is:

1. They are parallel to each other
2. Their magnitudes are not related
3. They are equal and opposite
4. They are perpendicular to each other x
5. They have the same magnitude
