Light foot traffic after 12 hours 24 to 48 hours Is it necessary to cure the screed after laying? No No Yes Standard joists-normally centers. Supporting battens are fitted between joists upon which rigid insulation is installed. Pipework is installed on the insulation and circuited via joist notching back to the manifold.

Some of the points that must be kept in mind during the process of cast designing are as follows: For variations it must be done gradually.

What are the points that should be kept in mind during forging design? Some of the points that should be followed while forging design are: Describe briefly the different cold drawing processes. Some of the important cold drawing processes are as follows: In the case of bar drawing the hot drawn bars are at first pickled, washed and coated to prevent oxidation.

Once this is done a draw bench is used for the process of cold drawing. In order to make an end possible to enter a drawing die the diameter of the rod is reduced by the swaging operation.

This end is fastened by chains to the draw bench and the end is gripped by the jaws of the carriage. In this method a high surface finish and accuracy dimensionally is obtained. The products of this process can be used directly without any further machining. Similar to the above process the bars are first pickled, washed and coated to prevent any oxidation.

After this the rods are passed through several dies of decreasing diameter to provide a desired reduction in the size diameter. The dies used for the reduction process is generally made up of carbide materials. This type of drawing is very similar to the bar drawing process and in majority of cases it is accomplished by the use of a draw bench.

What are the different theories of failure under static load, explain briefly? The main theories of failure of a member subjected to bi-axial stress are as follows: This theory states that failure occurs at a point in member where the maximum principal or normal stress in a bi-axial system reaches the maximum strength in a simple tension test.

This theory states that failure occurs when the biaxial stress reaches a value equal to the shear stress at yield point in a simple tension test.

This theory states that failure occurs when bi-axial stress reaches the limiting value of strain. This theory states that failure occurs when strain energy per unit volume of the stress system reaches the limiting strain energy point. This theory states that failure occurs when strain energy per unit volume reaches the limiting distortion energy.Objectives of Heat Treatments: Heat Treatment is the controlled heating and cooling of metals to alter their physical and mechanical properties without changing the product treatment is sometimes done inadvertently due to manufacturing processes that either heat or cool the metal such as welding or forming.

***Practical Training-1 & 2 (4-weeks each) done after 4th & 6th Semesters would be evaluated in 7th semester through Report and viva voice etc.

* Project should be initiated in 7th semester beginning, and should be completer by the end of 8th semester with good Report and power-point Presentation etc.

Specified Furniture A large proportion of furniture used within the scheme will be bespoke, having been crafted on site, but the need for practical, everyday use furniture is still integral. Heating, Ventilating, Air-Conditioning, and Refrigerating Engineering.

Mar. Refrigerants are the fundamental substances used to transfer heat during the mechanical cooling process. Chloroflurocarbon (CFC) compounds such as R and R have been used for decades in refrigeration cycles.
