It depends which gaps you mean! Older track was laid in discrete sections with gaps left between them to allow for expansion on hot days. There are gaps between rails at the points which are used to connect different tracks together in turn. Is this what you mean?
because of expansion and contraction.
The size of the gaps between railway sections decreases on a hot day. This is due to thermal expansion. Nowadays different composites are used and different methods employed when laying track so 'continuous' rails may be laid.
continuous
to allow for the thermal expansion or contraction
choosing 3 stations from 8... balance 8-3=5stations 5 stations have 4 gaps in between arrange these 3 (where it stops) in 4 gaps in 4C3=4 ways
railway station, Mumbai
no it doen't because there is little gaps in between and when it gets hot is expands and makes a full. track
Steel expands and changes shape as temperatures vary. On a hot day there's no gap, and overhead wires sag. On cold days, big gaps and straight wires... What u mean railway rails??
two section of railway track are joined together by welding.instead they are laid with gaps between them.fish plates,fastened by nuts and bolts which are able to slide along the oval holes,are used to join two section of railway track......
The graph of a continuous function will not have any 'breaks' or 'gaps' in it. You can draw it without lifting your pencil or pen. The graph of a discrete function will just be a set of lines.
Gaps or spaces in the soil are often referred to as pore spaces or soil pores. These gaps allow for the movement of air, water, and nutrients within the soil, playing a key role in supporting plant growth and ecosystem function.
You are referring to the gaps between two adjacent rails. Two reasons - 1) depending upon location, gaps are provided under "normal conditions" that will not exist when the rails become very hot (this is because of the rails expanding from heat); 2) gaps are provided which have insulating material inserted to separate rail sections into "blocks" to provide for control of systems such as the wayside signals.
