1.  An ideal transition curve is 

Answer: Option C Explanation: IRC recommends Spiral or clothoid as the ideal transition curve due to following reasons:
1. It satisfies that rate of change of centrifugal acceleration is constant i.e., L_{s}.R = constant. Where L_{s} = length of transition curve R = radius of curve. 2. The calculation and field implementation of spiral curve is simple and easy. 3. It enhances aesthetics also. 
2.  Pantagraph is used for
