The gradient resistance to a vehicle having a mass of 980 kg moving on an incline of 10° is
Discuss
Answer & 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.
