Unit 2.1 Statics

3. The turning effect of a force about a point equal to the magnitude of the force times the perpendicular distance from the point to the line of action from the force.
4. A truss that lies in a single plane often used to support roofs and bridges.
5. A support that prevents translation in any direction.
10. A body subjected to a pushing force.
13. A truss composed of triangles, which will retain its shape even when removed from supports.
14. The geometric center of an area.
15. A diagram used to isolate a body from its environment, showing all external forces acting upon it.
16. A strong rope, usually made of metal, designed to have great tensile strength and to be used in structures.
17. The connection points of members of a truss.

1. A condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity.
2. Three laws of motion that describe the relationship between the motion of an object and the forces acting on it.
6. A physical quantity that has magnitude and direction.
7. A plate or bracket for strengthening an angle in framework.
8. Slender straight pieces of a truss connected by joints.
9. A support that only prevents a beam from translating in one direction.
11. A body subjected to a pulling force.
12. A support that prevents translation and rotation in a beam.
13. A physical quantity that has magnitude only.
