CM 2113 WANG TEST 2 EXAM
QUESTIONS AND ANSWERS (VERIFIED
AND UPDATED)
Three basic components of soil - ANS solids, water and air
(T/F) For bulk materials, volumetric mesure varies with material's position in the construction
process - ANS T
(T/F) The same weight of a material will occupy different volumes as the material is handled on
the project - ANS T
Swell - ANS Reduction in density due to loosening the soil by digging
Which soil volume is used to determine the volume capacity of excavating/hauling equipment? -
ANS Loose Volume
Soil density is a measure of ? per unit of volume. - ANS Weight
What is soil's bank condition? - ANS Typical amount of soil in its natural state
(T/F) 1 bank cubic yard is 1 cubic yard of material after it has been disturbed by a loading
process - ANS F

, What are construction costs based on? - ANS (total quantity of the work to be done)*(the
unit price of the work)
Rolling Resistance - ANS resistance of a level surface to constant-velocity motion across it
What does rolling resistance result from? - ANS friction of the driving mechanism, tire flexing
and the force needed to push through or ride over the supporting surface
(T/F) rolling resistance applied to both crawler-type and wheel-type mobile equipment -
ANS T
(T/F) When a vehicle moves down a grade the force of gravity that assists the vehicle is also
called grade assistance - ANS T
(T/F)power required, total resistance and effective grade all denote the same thing - ANS T
(T/F) The decision process for matching the best possible machine to the project task requires
the engineer to take into account both the properties of the material to be handled and the
mechanical capabilities of the machine - ANS T
(T/F) The power to move a crawler type of tractor and load is called Rimpull - ANS F
Rimpull - ANS the tractive force between the tires of a machine's driving wheels and the
surface on which they travel
Drawbar Pull - ANS towing force a crawler tractor can exert on a load
Bank Soil - ANS natural state, before being undisturbed used for performing quantity take offs
