CM 2113 Wang Test 2 questions and answers
2026\2027 A+ Grade
Three basic components of soil
- correct answer solids, water and air
(T/F) For bulk materials, volumetric mesure varies with material's position in the construction process
- correct answer T
(T/F) The same weight of a material will occupy different volumes as the material is handled on the
project
- correct answer T
Swell
- correct answer Reduction in density due to loosening the soil by digging
Which soil volume is used to determine the volume capacity of excavating/hauling equipment?
- correct answer Loose Volume
Soil density is a measure of ? per unit of volume.
- correct answer Weight
What is soil's bank condition?
- correct answer 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
- correct answer F
, What are construction costs based on?
- correct answer (total quantity of the work to be done)*(the unit price of the work)
Rolling Resistance
- correct answer resistance of a level surface to constant-velocity motion across it
What does rolling resistance result from?
- correct answer 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
- correct answer T
(T/F) When a vehicle moves down a grade the force of gravity that assists the vehicle is also called grade
assistance
- correct answer T
(T/F)power required, total resistance and effective grade all denote the same thing
- correct answer 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
- correct answer T
(T/F) The power to move a crawler type of tractor and load is called Rimpull
- correct answer F
Rimpull
- correct answer the tractive force between the tires of a machine's driving wheels and the surface on
which they travel
Drawbar Pull
- correct answer towing force a crawler tractor can exert on a load
