Stopping Sight Distance on Level Ground with Breaking Efficiency Solution

STEP 0: Pre-Calculation Summary

Formula Used

Stopping Sight Distance = Speed of Slow moving vehicle*Break Reaction Time+(Speed of Slow moving vehicle^2)/(2*[g]*Design Coefficient of Friction*Overall Efficiency from Shaft A to X)
SSD = V_b*t+(V_b^2)/(2*[g]*f*η_x)
This formula uses 1 Constants, 5 Variables

Constants Used

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

Variables Used

Stopping Sight Distance - (Measured in Meter) - Stopping Sight Distance is defined as distance provided on the road before a sharp turn.
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.
Break Reaction Time - (Measured in Second) - Break Reaction Time is defined as time taken by the driver to apply the break.
Design Coefficient of Friction - Design Coefficient of Friction is a dimensionless number that is defined as the ratio between friction force and normal force.
Overall Efficiency from Shaft A to X - The Overall efficiency from shaft A to X, of a gearbox, depends mainly on the gear mesh and bearings efficiency.

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
Break Reaction Time: 2.5 Second --> 2.5 Second No Conversion Required
Design Coefficient of Friction: 0.15 --> No Conversion Required
Overall Efficiency from Shaft A to X: 0.8 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

SSD = V_b*t+(V_b^2)/(2*[g]*f*η_x) --> 11.11*2.5+(11.11^2)/(2*[g]*0.15*0.8)

Evaluating ... ...

SSD = 80.2190473216304

STEP 3: Convert Result to Output's Unit

80.2190473216304 Meter --> No Conversion Required

FINAL ANSWER

80.2190473216304 ≈ 80.21905 Meter <-- Stopping Sight Distance
