Q148
The gradient resistance to a vehicle having a mass of 980 kg moving on an incline of 10° is
A.
1.6694 N
B.
16.694 N
C.
166.94 N
D.
1669.4 N
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
Given data:Mass = 980 kg
Angle of inclination = 10°
Equation we used is,
Gradient resistance is given by Gr = W sin (angle of inclination)
Gr = 980 × sin (10)
= 170.175 kg × 9.81
= 1669.41 N.
