2 cards from this section. Quick, good the night before a test.
Define grade compensation.
Think about both gradient and curve interactions.
What is the IRC specification for grade compensation under 4%?
Consider how traction is affected at different inclines.
What is the maximum grade compensation allowed according to IRC?
Consider the IRC limits set on gradient ratios.
Is grade compensation needed for gradients less than 4%?
Think about how slopes affect traction force.
A road segment has a horizontal curve of radius 25 meters and a gradient of 8%. Determine the grade compensation and discuss its implications.
Consider the forces acting on the vehicle while navigating the curve.
Design a road in a hilly terrain where curves are present. How would you incorporate grade compensation for multiple high gradients?
Think about adjustments for vehicle traction needing to be safe and efficient.
