what is the pitch point
Clients in a full mesh have a direct connection with all other clients in the mesh. while a partial mesh does only have some connections with other clients in the mesh.
Mesh
I wish the answer was more exciting, the plural of mesh is simply "meshes"
mesh 500 micron=31 inches=0.0012
where the gears are always engaged.
In a synchromesh gearbox, synchronizers are used to match the speed of gears before engaging, resulting in smoother and quieter gear shifts. Constant mesh gearboxes have gears that are always in mesh, with dog clutches used to engage gears for selection, which can be quicker but may be noisier.
Sliding mesh - This is where the gears are not in constant mesh with each other and the gears on the main shaft slide over to mesh with the gears on the lay shaft/counter shaft. Synchromesh - the problem with constant mesh is that the gears crash into each other when changing gear because there travelling at different rpms (one at engine speed and the other a lot slower) They dont line up properly when spinning and when they go to mesh they end up grinding. So the awnser is Synchromesh which uses Baulk rings to lock onto the gear first before the sliding sleeve comes over to lock on. Difficult to explain how it works but basically its a smooth gear change.
meshing gears
Matching the gears to mesh properly.
Sliding Gears in a transmission are straight-tooth spur gears with a taper (also known as a lead) to make engaging easier. Helical gears are mostly used in a transmission because spur gears produce gear noise and have a great strain on the teeth of the gear since only one tooth can be in contact at any given time. But because helical gears cannot be taken out of mesh, spur gears are used for the reverse gear because reverse spins the opposite way and cannot be in constant mesh.
Reverse gear is spur because it has to slide, sliding mesh gearbox uses spur gears. Because if it was constant mesh gear (helical) it could not slide in and out, therefore it could not go in the opposite direction of rotation.
Don't really know what you're tinking of with "mesh together"... On a bike with external gears the gears will not mesh. There's the chain acting as a go-between to transfer the energy. On an internally geared bike you will have cogwheels that are interlocking and driving each other.

Crown and pinion gears are two types of mechanical gears that mesh together.
a crown and pinion is a st of gears that mesh at an angle.
Usually a single part made up of a serious of Gears that mesh with various gears of main shaft
