Coefficient of Friction given Stopping Sight Distance Solution

STEP 0: Pre-Calculation Summary

Formula Used

Design Coefficient of Friction = (Speed of Slow moving vehicle^2)/(2*[g]*(Stopping Sight Distance-(Speed of Slow moving vehicle*Break Reaction Time)))
f = (V_b^2)/(2*[g]*(SSD-(V_b*t)))
This formula uses 1 Constants, 4 Variables

Constants Used

[g] - Gravitational acceleration on Earth Value Taken As 9.80665

Variables Used

Design Coefficient of Friction - Design Coefficient of Friction is a dimensionless number that is defined as the ratio between friction force and normal force.
Speed of Slow moving vehicle - (Measured in Meter per Second) - Speed of Slow moving vehicle is the speed of vehicle which has to be overtaken.
Stopping Sight Distance - (Measured in Meter) - Stopping Sight Distance is defined as distance provided on the road before a sharp turn.
Break Reaction Time - (Measured in Second) - Break Reaction Time is defined as time taken by the driver to apply the break.

STEP 1: Convert Input(s) to Base Unit

Speed of Slow moving vehicle: 11.11 Meter per Second --> 11.11 Meter per Second No Conversion Required
Stopping Sight Distance: 160 Meter --> 160 Meter No Conversion Required
Break Reaction Time: 2.5 Second --> 2.5 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f = (V_b^2)/(2*[g]*(SSD-(V_b*t))) --> (11.11^2)/(2*[g]*(160-(11.11*2.5)))

Evaluating ... ...

f = 0.0475952783406742

STEP 3: Convert Result to Output's Unit

0.0475952783406742 --> No Conversion Required

FINAL ANSWER

0.0475952783406742 ≈ 0.047595 <-- Design Coefficient of Friction
