Angular velocity = 7.3 x 10 -5 rad/s. thus, the speed of any point on the earth's surface at the equator due to earth's rotation is, V = r $\omega$ = 6.4 x 10 6 x 7.3 x 10 -5 m/s = 470 m/s. The examples based on Rotational Speed are given below : Back to Top.
Sarking is a layer of flexible insulation typically installed under roof tiles when a home is being constructed.It consists of aluminum foil laminated onto paper or plastic backing with a flame retardant adhesive and fibreglass reinforcing mesh, and is manufactured in sheet form.Sarking performs a dual function, helping to keep your home insulated from the heat of summer whilst retaining warmth in the winter.t consists of aluminum foil laminated onto paper or plastic backing with a flame retardant adhesive and fibreglass reinforcing mesh, and is manufactured in sheet form.

The term âsarkingâ is used in several different ways in construction. In general, it is a panel which is used as an underlayment, and may be used in the construction of walls, or in the construction of a roof. In walls, people may refer to âscrim and sarkingâ construction, a technique used in many older homes.People doing refurbishment and repair of such homes may opt to reproduce this building technique to preserve the character of the structure. On a roof, sarking is used as part of the underlayment or roof membrane.It acts as a barrier to prevent moisture from entering the roof and the home, and also helps to reflect heat.n walls, sarking is put up in the form of flat panels which historically were covered in a fabric material known as scrim. Wallpaper, plaster, or other finishes could be applied directly to the scrim and sarking.
