1. Accommodating the type and MAGNITUDE of the to which the structure will be
subjected is the most critical aspect of engineering design: FORCES
2. The ability to understand and evaluate these forces distinguishes a
knowledge of buildings from a knowledge: casual
professional
3. In physics: Any interaction that may change the motion of an object: -
FORCES
4. Any effect that a structure must be designed to resist, including the forces of gravity, wind, earthquakes, or
soil pressure.: LOAD
5. Any effect that a structure must be designed to resist, including the forces of , , or
pressures: gravity, wind, earthquakes or soil pressures
6. Factors that work against the strength of any piece of apparatus, equipment, or structural support.: STRESS
7. Measurement of force intensity is
calculated as DIVIDED BY :-
FORCE DIVIDED BY AREA
8. Condition of balance that exists when a structural system is capable of supporting the applied load:
EQUILIBIRIUM
9. must equal or surpass the applied to achieve structural equilibri- um:
REACTIONS
LOADS
10. applied load on a beam will stress each of the supports equally.: UNI- FORMLY
11. To calculate the structural supports needed to allow a building to with- stand common , loads are
categorized and calculated: FORCES
12. To calculate the structural supports needed to allow a building to with- stand common FORCES, are
categorized and calculated: LOADS
13. LOADS ARE AND : CATEGORIZED AND CALCULATED
14. The forces within a structural support system that resist applied loads are referred to as : REACTIONS
15. When a structural support system can support a load equal to or greater than the applied loads L, ex- ists:
EQUILIBRIUM
16. Loss of equilibrium can lead to partial or total collapse. In a sense, when the building into a pile of debris on
the ground, is reestablished.: - EQUILIBRIUM
