They're coupled to each other. The type of coupler depends on both which country you're in and what kind of service the train is in. Americans tend to use a loose (semi-automatic) coupler called the knuckle - whereas the Europeans tend to use a hook and link along with buffers: this reduces the slack space between cars.
In addition to the mechanical connection, there are also other connections, esp on passenger cars. All cars have a train brake connection. Passenger cars may receive electricity and/or steam heat.
yes
The last top answer just did not answer the question being asked, I understand that you want specifics when it comes to each class and the last guy just didn't understand that, but from my readings it seems that a class 3 has a mechanical disadvantage meaning it takes a stronger force to lift a smaller amount of resistance. What third class levers lack in lifting power it makes up with high velocity situations such as throwing something. meaning it is good with speed. Sorry but I have yet to figure out the other 2 classes
in this stress the force acts parallel to the area on which the stress is measured. microscopically what takes place is that the material is made of several planes and during the shear stress the planes slip over each other like a pack of cards until finally failing.
You cannot have a general answer for this. The comparison in strength depends on the chemical composition or grade of each, as well as the heat treatment and quenching method each received.
A reciprocating compressor is basically a piston pump, much like if you'd take an average internal combustion engine and force it to run. A scrolling compressor uses two plates with a spiral-wound raised ledge on them. The ledges overlap and as they move in relation to each other air gets squeezed further and further into the labyrinth until it reaches the outlet port.
Depends how many wagons or carriages a train has. A goods wagon can have 4 wheels, but 8 is more usual, 4 on each of 2 bogies. A passenger carriage normally has 8, 4 on each of 2 bogies. A locomotive has 8 or 12, 4 or 6 on each of 2 bogies. Then multiply by the number of vehicles in the train. For example, a 12-car passenger train has 96 wheels. Other arrangements are possible, where a bogie of 4 wheels is shared between two adjoining carriages, for example on French TGV high speed trains. This gives greater stability at high speeds.

They connect to each other in DNA.
Nucleotide molecules connect with each other in phosphate. Nucleotides are composed of three parts: phosphate, deoxyribose and the nitrogen base.

You connect each computer to a switch, using a UTP cable. Some small switches only have 8 ports; you can connect two such switches to each other, with an additional cable. Each computer has to have a network card.You connect each computer to a switch, using a UTP cable.

Excel spreadsheets consists of "cells". Each box is a cell. Cells that are stacked on top of each others like floors in a high building are called a column. And cells that are strung out end to end like carriages on a train are called rows.
