Answer:

80grit

Explanation:

80 grit is coarsest grit that may be used on aluminum

The lowest grit sizes range from 40 to 60. From the given options 80 grit is practically available grit.

What is a sandpaper used for?

They are essentially used for surface preparation. Sandpaper is produced in a range of grit sizes and is used to remove material from surfaces, either to make them smoother (for example, in painting and wood finishing), to remove a layer of material (such as old paint), or sometimes to make the surface rougher (for example, as a preparation for gluing).

Steam enters a heavily insulated throttling valve at 11 MPa, 600Â°C and exits at 5.5 MPa. Determine the final temperature of the

7nadin3 [17]

Answer: the final temperature of the steam 581.5 °C

Explanation:

Given that;

P₁ = 11 MPa

T₁ = 600°C

exit at; P₂= 5.5 MPa

Now from superheated steam table( p=11 MPa, T=600°C)

h₁ = 3615 kJ/kg

h₁ = h₂ ( by throttling process and adiabatic isentholpic )

from saturated steam table at; ( h= 3615 kJ/kg, P= 5.5 MPa )

Temperature = 581.5 °C

Therefore the final temperature of the steam 581.5 °C

A horizontal rigid bar ABC is pinned at end A and supported by two cables at points B and C. A vertical load P 5 10 kN acts at e

BARSIC [14]

Answer:

vertical load = 10 kN

Modulus of elasticity = 200GPa

Yield stress on the cable = 400 MPa

Safety factor = 2.0

Explanation:

Data

let L = $\sqrt{(1.5)^{2} + (1.5)^{2} }$

= 3.35 m

substituting 1.5 m for h and 3 m for the tern (a + b)

$\theta$ = tan⁻¹( $\frac{1.5}{1.5}$ )

= 45⁰

substituting 1.5 for h and 3 m for (a+ b) yields:

$\theta$ ₂ = tan⁻¹ ( $\frac{1}{3}$ )

=25.56⁰

checking all the forces, they add up to zero. This means that the system is balanced and there is no resultant force.

On a ship the price gift is 24 euros .What is the difference in the price on a day when the exchange rate is £1=2378

bija089 [108]

Answer:

The answer is " $\$29.7072$ ".

Explanation:

Please find the complete question in the attachment file.

As the original prices are 24 euros, $\$ 1.2378$ must be multiplied by 24.

$\to 1.2378 \times 24 = \$29.7072$

Therefore the new price value will be $\$ 29.7072$
