What is the difference between flexible and rigid pavements?
Flexible pavement: Are those pavements which reflect the deformation of subgrade and the subsequent layers to the surface. Rigid pavement: The rigid characteristic of the pavement are associated with rigidity or flexural strength or slab action so the load is distributed over a wide area of subgrade soil.
What is the difference between rigid electrical pipe and plumbing pipe?
The threads
What are types of mechanical coupling?
There are many like flexible coupling, jaw coupling, sleeve coupling, tire coupling, pin and bush coupling, rigid coupling, etc
What is a coupling?
couplings are used to join sections of long transmission shafts. couplings are also used to connect the shaft of a driving machine to the shaft of a separately built machine so as to give an effect of continuous shaft. the general classification of couplings is as given under: 1. rigid coupling 2. flexible coupling 3.Camlock coupling
