17.2.2. Representation of gradient

Try these first

1. 1.

   Define what a positive gradient is.

   Hint

   Think about the direction the road is going.

2. 2.

   What does a negative gradient represent?

   Hint

   Consider if the elevation is going down.

3. 3.

   What does a positive gradient represent?

   • Descending road
   • Ascending road
   • Flat road

   Hint

   Visualize if you're climbing uphill.

4. 4.

   The deviation angle is calculated as what?

   Hint

   Think about how two slopes can meet.

5. 5.

   Vehicle A operates at a stable speed on a +6% gradient, while Vehicle B operates on a -3% gradient. Calculate the deviation angle when the two vehicles meet at a junction.

   Hint

   Remember to consider the signs of both gradients.

6. 6.

   You are tasked to design a road where two gradients intersect, one at +4% and another at -2%. How would you convey this in a design plan?

   Hint

   Think about what makes logical sense for vehicle speed and safety.
