Answer:

Steel can rusts easily in the presence of moisture and oxygen, and tarnishes as the rust progresses.

Explanation:

Steel is an alloy of carbon and iron. it is a very useful alloy that is found in almost any engineered piece. The problem with steel is that it is very susceptible to rust, and the cost of maintaining it in order to prevent rust is very high. Steel rusts in the presence of moisture and oxygen (rust is an oxidation-reduction process). Using it as a water slide exposes it constantly to moisture, and to prevent it from rusting in this case will involve a lot of maintenance cost, which is why steel is not advisable to be used in this case.

A 2m high sandy fill material was placed loosely at a relative density of 47%. Laboratory studies indicated that the maximum and

Llana [10]

Answer:

2

Explanation:To find the solution we must first make the transformations to international units,

In this way:

Inches of length (L) to feet =

So we can identify the area by hour:

Once the area is identified, we now identify the number of passes required,

Passes required = Area x number of passes

We transform speed to international units

So we can identify the covered area

where

m = drum widht

p = efficiency

In this way we obtain the number of rollers given by:

No. of Rollers = Passes required / covered area

No of rollers = 48136/40269

No of rollers = 1.19, that is, 2
