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.
Where i use the expansion joint?
Expansion joints are used in various types of structures and systems to accommodate the movement caused by thermal expansion, contraction, vibrations, settlement, or other dynamic forces. They are designed to prevent damage to the structure by allowing controlled movement while maintaining the structural integrity. Here are some common applications where expansion joints are used: **Buildings and Structures**: **Buildings**: Expansion joints are used in buildings to accommodate the movement caused by temperature changes and structural settling. They are often found in floors, walls, ceilings, and facades. **Bridges**: Expansion joints are critical in bridges to allow for the movement of the bridge components due to temperature fluctuations, traffic loads, and seismic activity. **Roads and Highways**: Expansion joints are used in roadways and highways to prevent cracking and damage due to thermal expansion and contraction. They also accommodate the movement caused by heavy traffic loads. **Piping Systems**: **Industrial Pipelines**: Expansion joints are installed in piping systems to absorb thermal expansion and contraction of pipes caused by temperature changes in the fluid being transported. **HVAC Systems**: In heating, ventilation, and air conditioning systems, expansion joints help compensate for the expansion and contraction of ductwork due to temperature changes. **Railways and Transit Systems**: **Railway Tracks**: Expansion joints are used in railway tracks to allow the rails to expand and contract with temperature changes. This helps prevent buckling and warping of the tracks. **Subway and Light Rail Systems**: Expansion joints are used in tunnels and station structures to accommodate the movement caused by ground settlement and vibrations. **Water and Wastewater Systems**: **Water Treatment Plants**: Expansion joints are used in water and wastewater treatment facilities to handle the movement of pipes and structures due to changes in water pressure, temperature, and ground settlement. **Aerospace and Transportation**: **Aircraft**: Expansion joints are used in aircraft components to accommodate the movement caused by changes in air pressure and temperature during flight. **Automobiles**: Expansion joints are found in exhaust systems and other components to absorb vibrations and thermal expansion. **Industrial Facilities**: **Manufacturing Plants**: Expansion joints are used in industrial facilities to allow for the movement of equipment, machinery, and structures due to temperature changes and vibrations. **Power Plants**: Expansion joints are used in power plants to handle the movement of pipes, boilers, and other components caused by temperature changes and pressure differentials. **Marine Structures**: **Harbors and Ports**: Expansion joints are used in dock structures and seawalls to accommodate tidal fluctuations and other dynamic forces. **Shipbuilding**: Expansion joints are used in shipbuilding to accommodate movement in the hull and other components. These are just a few examples of the many applications of expansion joints. The specific type of expansion joint used will depend on the requirements of the structure or system, the type of movement expected, and other factors. Proper design, installation, and maintenance of expansion joints are essential to ensure the longevity and functionality of the structure or system.

Are there guard rails on the road to Positano?
yes
What are the guard rails on a ship called?
They're called taff rails, especially at the stern of the ship
What are the stile and rail of a door?
the stiles are vertical and the rails are horizontal, in other words, the stiles are the side pieces and the rails are the cross pieces
Why are there a second set of rails inside of the main rails when tracks cross a trestle and what is this called?
The inside rails inside of the main rails are called guard rails. They are there so that if there is a derailment the train will stay within the rails instead of off of the trestle.
Who invented the guard rails attachment for beds and carriages?
alfred l cralle
How many rails on a track?
2 running rails. There may be a power rail ("the third rail") There may be guard rails at places like bridges and curves (there always are short ones at turnouts ("switches").
What is the required height for outside step rails?
In most areas it is 40 inches
Why are their guard rails used to protect the baby pigs?
they are there so when the sow rolls over, she doesn't accidentally squish the piglets
What determines where guard rails are placed on highways?
The danger and chance of off road collisions, amount of traffic, and the cost to put them in.
