Q: Which of the following are CORRECT values for coefficient of lateral and longitudinal friction as per IRC?
  • A. 0.10, 0.15
  • B. 0.15, 0.35
  • C. 0.30, 0.10
  • D. 0.35, 0.15
Correct Answer: Option B - As per IRC, (i) The value of coeff of lateral friction = 0.15 (ii) The value of coeff of longitudinal friction = 0.35
B. As per IRC, (i) The value of coeff of lateral friction = 0.15 (ii) The value of coeff of longitudinal friction = 0.35

Explanations:

As per IRC, (i) The value of coeff of lateral friction = 0.15 (ii) The value of coeff of longitudinal friction = 0.35
