CM 2501 - Hebert - Final Exam
Questions All Answered Correct
Graded A+.
live - Answer Gravity load that can be removed from a structure such as people and
furniture.
dead - Answer Gravity load that cannot be removed from a structure such as walls and
floors.
wind - Answer Lateral loads caused by _____ vary in intensity with the building's height,
location, and shape.
earthquake - Answer Lateral load that impacts buildings at grade level and acts in a
"shaking" manner upon the superstructure.
thermal - Answer Type of load that results from changes in temperature causing structural
members to change shape and push and pull on other parts.
settlement - Answer Load causing a structure to sink into the ground and change shape.
dynamic - Answer Type of load that changes over time.
tensile - Answer Stress from two opposing forces pulling or stretching a member.
compression - Answer Stress from two opposing forces pushing or squeezing a member.
shear - Answer Stress that tends to move in layers in different directions
bending - Answer Stress that is a combination of tensile, compression, and shear and is least
efficient structurally.
bending, shear (more in bending) - Answer Beams are stressed in:
compression - Answer Columns are stressed in:
, tension - Answer Cables are stressed in:
compression - Answer Arches are stressed in:
tension, compression - Answer Trusses are stressed in:
membrane (tension and/or compression evenly distributed through the shell thickness) -
Answer Shells are stressed in:
equilibrant - Answer A single vector that is equal in magnitude but opposite in sense to the
resultant of all forces acting on a body.
resultant - Answer A single vector that is an equal replacement of a group of vectors that has
the same external effect.
force, distance - Answer The units of a moment are a _____ times a _____. ex: k-ft, N-m
1 pin, 1 roller - Answer A typical stable and determinant simple beam will have what
supports?
greater - Answer If a roof rafter with a 20° slope has a total load of 15 lb/ft along the slope,
will the total load along the horizontal projection be greater than, less than, or equal to 15 lb/ft?
equal to - Answer The magnitude of the equilibrant is _____ the magnitude of the resultant.
statics - Answer Part of mechanics that is the study of forces and the effect of those forces
on bodies.
moment - Answer A tendency to rotate or twist.
couple - Answer A pair of parallel forces equal in magnitude and opposite in direction
displaced by a perpendicular distance. They produce only rotation, no translation.
cantilever - Answer A _____ has three reactions. Two independent component reactions
(x,y) and one moment reaction.
simple beam - Answer A _____ _____ has two supports and three reactions. Supports are
typically 1 pin with two reactions x,y and 1 roller with one reaction y.
