There are many different types of transition curves but...
'Transition Curve', a simple tool used to understand the sorts of issues people might be facing during change
A track transition curve, transition spiral, or spiral easement, is a mathematically calculated Euler spiral fitted between a straight (also known as tangent) and a circular curve on a section of rail track or highway.

What is curve ranging?
In highways, railways, or canals the curve are provided for smooth or gradual change in direction due the nature of terrain, cultural features, or other unavoidable reasons. In highway practice, it is recommended to provide curves deliberately on straight route to break the monotony in driving on long straight route to avoid accidents. The horizontal curve may be a simple circular curve or a compound curve. For a smooth transition between straight and a curve, a transition or easement curve is provided. The vertical curves are used to provide a smooth change in direction taking place in the vertical plane due to change of grade.
Why is a transition curve required in a railway track?
Not being an engineer but having worked at a narrow-gauge and diesel railway theme park, I know that it was because of the mountain curves that narrow-gauge rails were used in logging to accommodate them because the larger gauge rails could not; "transition curve" sounds like it's a very gradual turn that ever narrows into the required tighter radius.
What is the purpose of pointing up brickwork?
Apart from tidying up the look of the bricks and mortar, pointing up puts a slight slope or curve on the mortar to prevent rain water from settling.
Assumptions of ultimate load method?
1. Plane sections normal to axis remain plane after bending. This implies that strain is proportional to the distance from neutral axis. 2. Maximum strain in concrete of compression zone at failure is 0.0035 in bending 3. Tensile strength of concrete is ignored. 4. The stress-strain curve for the concrete in compression may be assumed to be rectangle, trapezium, parabola or any other shape which results in prediction of strength in substantial agreement with test results.
