Q92
The coefficient of rolling resistance for a truck weighing 63,500 N is 0.018. The rolling resistance to the truck is
A.
1.143 N
B.
11.43 N
C.
114.3 N
D.
1143 N
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
As per given data,Truck weight = 63500 N.
Coefficient of rolling = 0.018
Equation: Rolling resistance = Coefficient of rolling × weight
Rolling resistance = 0.018 × 63500 = 1143 N
