a continuously reinforced concrete pavement cross-section contains a layer of no. 6 reinforcing bars at 6-inch centers, such that the steel is just above mid-depth of a 10-inch thick slab. cover over the top of the steel is therefore about 4 inches.

Answers

Answer 1

The concrete pavements has a layer of no. 6 reinforcing bars placed at 6-inch intervals, just above the center of a 10-inch thick slab, with about 4 inches of cover over the steel.

In a continuously reinforced concrete pavement cross-section, the primary purpose of the reinforcing bars is to control and distribute cracking caused by the tensile forces that develop in the concrete slab as a result of temperature changes and traffic loads. In this specific case, the cross-section contains no. 6 reinforcing bars, which refers to bars with a diameter of 0.75 inches.

These bars are spaced at 6-inch centers, meaning that the distance between the centers of adjacent bars is 6 inches. By positioning the steel just above mid-depth of the 10-inch thick slab, it ensures that the reinforcing bars are in an optimal location to effectively resist tensile stresses.

The cover over the top of the steel refers to the distance between the surface of the concrete slab and the top surface of the reinforcing bars. In this case, the cover measures approximately 4 inches. This cover plays a crucial role in protecting the steel from corrosion and providing fire resistance.

The density of titanium is 4.51g/cm^3. What is the volume (in
cubic inches) of 3.5lb of Titanium? this could be helpful D=M/V

Answers

The volume of 3.5 lb of titanium is 21.47 in³.

The density of titanium is 4.51 g/cm³.The weight of titanium is 3.5 lb.

Formula used:

Density, D = M/V, where D is density, M is mass, and V is volume.

The conversion factor of 1 inch³ = 16.39 cm³.1 lb = 453.592 g.

First, we will calculate the mass of titanium.

3.5 lb = 3.5 × 453.592 g

= 1587.772 g

Next, we will calculate the volume of titanium.

Volume of titanium = Mass of titanium / Density of titanium

= 1587.772 g / 4.51 g/cm³

= 352.044 cm³

Next, we will convert the volume from cm³ to in³.

1 inch³ = 16.39 cm³.

Volume of titanium in in³ = Volume of titanium / 16.39

= 352.044 cm³ / 16.39

= 21.47 in³

A compound consisting of carbon and hydrogen consists of 67.90%
carbon by mass. If the compound is measure to have a mass of 37.897
Mg, how many grams of hydrogen are present in the compound?

Answers

Given that the compound consists of 67.90% carbon by mass and has a total mass of 37.897 Mg, we can calculate the mass of hydrogen in the compound.

Let's assume the mass percentage of hydrogen in the compound is denoted by "y." According to the law of constant composition, the sum of the mass percentages of carbon and hydrogen is equal to 100.

Mass% of Carbon + Mass% of Hydrogen = 100

Since the mass percentage of carbon is 67.90%, we can calculate the mass percentage of hydrogen as follows:

Mass% of Hydrogen = 100 - 67.9

Mass% of Hydrogen = 32.1

Therefore, the compound contains 32.1% of hydrogen by mass.

Next, we can calculate the mass of hydrogen present in the compound using the following formula:

Mass of hydrogen = Percentage of hydrogen x Total mass of the compound / 100

Substituting the given values, we find:

Mass of hydrogen = 32.1 x 37.897 Mg / 100

Now, we need to convert the mass from megagrams (Mg) to grams:

Mass of hydrogen = 32.1 x 37.897 Mg x 10^6 g / 100

Calculating this expression, we find:

Mass of hydrogen = 12.159 grams

There are 12.159 grams of hydrogen present in the compound.
