Select the numbers belоw оnly fоr the TRUE stаtements. 1. If the net force on а rigid body is zero but the net moment аbout some arbitrary point is non-zero, the body can still be in static equilibrium. 2. When writing scalar equilibrium equations in 3 D, one can always choose a coordinate system aligned with two non-parallel forces to reduce the number of unknown components. 3. At a point where the internal shear force diagram crosses zero, the corresponding bending moment diagram reaches a local extremum. 4. The moment of inertia of a body about an arbitrary axis is always smaller than its moment of inertia about any axis passing through its centroid. 5. For planar (lamina) bodies, the polar moment of inertia about an axis perpendicular to the plane equals the sum of the planar moments I_x + I_y. 6. The centroid of a composite area can be found by summing the first moments of each sub-area about the reference axes, regardless of whether individual sub-areas overlap. 7. Six independent scalar equations of equilibrium (three force, three moment) are required and sufficient to solve any statically determinate 3-D rigid-body system.
