CM 2113 WANG TEST 2 2026 EXAM
PREPARATION PACK KEY TOPICS AND SAMPLE
QUESTIONS WITH EXPLANATIONS
◉ What are construction costs based on. Answer: (total quantity of
the work to be done)*(the unit price of the work)
◉ Rolling Resistance. Answer: resistance of a level surface to
constant-velocity motion across it
◉ What does rolling resistance result from?. 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. Answer: T
◉ (T/F) When a vehicle moves down a grade the force of gravity that
assists the vehicle is also called grade assistance. Answer: T
◉ (T/F)power required, total resistance and effective grade all
denote the same thing. 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. Answer: T
◉ (T/F) The power to move a crawler type of tractor and load is
called Rimpull. Answer: F
◉ Rimpull. Answer: the tractive force between the tires of a
machine's driving wheels and the surface on which they travel
◉ Drawbar Pull. Answer: towing force a crawler tractor can exert on
a load
◉ Bank Soil. Answer: natural state, before being undisturbed used
for performing quantity take offs
◉ Loose Soil. Answer: has been excavated or loaded, used to
determine the volume capacity of the excavating and hauling
equipment
◉ Compact Soil. Answer: after comparison, used to determine the
volume of any structure such as a damn or a fill
