CM 2113 WANG TEST 2 QUESTIONS
WITH VERIFIED SOLUTIONS 2026
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
, 2
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
the primary factors thatdetermine the power available at the drive wheels
(drawbar) of a machine are? - correct-answer - Engine horsepower and operating
gear
Maximum usable tractive force= - correct-answer - =F x CT (F= load on drive axles
in pounds- CT = coefficient of traction)
