1.

The vertical loads, due mainly to the occupancy, self-weight and snow or rain, are commonly referred to as

(a)  

2.

consist of the weight of the various structural members and the weights of any objects that are permanently attached to the structures.

(a)  

3.

can vary both in their magnitude and location. They may be caused by the weights of the objects temporarily placed on a structure, moving vehicles, or natural forces.

(a)  

4.

In some parts of the country, roof loading due to snow and rain can be quite severe, and therefore, protection against possible failure is of primary concern.

(a)  

5.

When structures are used to retain water, soil or granular materials, the pressure developed by these loadings becomes an important criterion for their design.

(a)  

6.

When live loads are applied rapidly to a structure, they cause larger stresses than those that would be produced if the same loads would have been applied gradually. The dynamic effect of the load that causes this increase in stress in the structures is called

(a)  

7.

When structures block the flow of wind, the winds kinetic energy is converted into potential energy of pressure, which causes a wind loading. The effect of wind on a structure depends on the velocity of the air, the angle of incidence of the wind, the shape and stiffness of the structure, and the toughness of its surface.

(a)  

8.

Earthquakes produce loadings on a structure through its intersection with the ground and its response characteristics. These loadings result from structure distortion caused by the ground’s motion and the lateral resistance of the structure

(a)  

9.

is a loading that exist along the full length or longitudinal axis of a beam.

(a)  

10.

is a loading that is perpendicular to the longitudinal axis of a beam.

(a)  

11.

a force applied at a very small portion on abeam

(a)  

12.

a load that is distributed or spread across the whole region of a beam.

(a)  

13.

a load that spread over the beam which is linearly varying from one end to the other end.

(a)  

14.

allows rotation and horizontal forces but will resist vertical forces.

(a)  

15.

allows rotation but will resist horizontal forces and vertical forces

(a)  

16.

is a rigid connection that will resist all forces on the horizontal, vertical, and rotational forces.

(a)
