Built-up roofing, also called BUR, is the most common roofing material used on low-slope roofs. It is composed of alternating layers of reinforcing fabric and bitumen (asphalt) and is finished with a top layer of aggregate, such as stone or gravel.

Resistance to impact is an example of a(n)

Anika [276]

Answer:

Mechanical property

Explanation:

MECHANICAL PROPERTIES can be defined as the ability of a metal or material to remain undamaged after different type of forces has been applied or used on them because forces or loads are often applied to metal, material or physical properties which is why MECHANICAL PROPERTIES enables us to know the strength , toughness as well as the hardness of metal and the way this metal perform or react when different forces are applied on them.

Lastly any metal, material or physical properties that has the strength , hardness and resistance to withstand or remain unaffected despite the loads or forces use on them is an example of MECHANICAL PROPERTIES.

Therefore Resistance to impact is an example of a(n) MECHANICAL PROPERTIES.

A 7-cm diameter horizontal pipe connected to the side of a tank at 4 m below the water surface in the tank discharges water to t

Anna11 [10]

Answer:

47.10 m/s

Explanation:

Diameter of the horizontal pipe, d = 7 cm = 0.07 m

Area of the horizontal pipe, A = $\frac{\pi}{4}d^2$

A = $\frac{\pi}{4}0.07^2$ = 0.00384 m²

Head between the water surface and the pipe level, z = 4 m

Head added by the pump, hp = 8 - 200Q²

where, Q is the discharge

losses, hL = 5 m

now,

applying the Bernoulli's theorem between the water surface and the pipe outlet,

we have

$\frac{P_1}{\rho}+\frac{V_1^2}{2g}+z+h_P=\frac{P_2}{\rho}+\frac{V_2^2}{2g}+h_L$

where,

P₁ = pressure at the water surface = 0 (as atmospheric pressure only)

V₁ = Velocity at the free surface = 0

ρ is the density of the water

P₂ = pressure at the outlet = 0 (as atmospheric pressure only)

V₂ = Velocity at the outlet

on substituting the values, we get

$z+h_P=\frac{V_2^2}{2g}+h_L$

$4+(8-200Q^2)=\frac{V_2^2}{2\times9.81}+5$

$7-200Q^2=\frac{V_2^2}{2\times9.81}$

also,

Q = A × V₂

thus,

$7-200\times(0.00384\times\ V_2)^2=\frac{V_2^2}{2\times9.81}$

V₂ = 47.10 m/s

The steel bracket is used to connect the ends of two cables. if the allowable normal stress for the steel is sallow = 30 ksi, de

The largest tensile force that can be applied to the cables given a rod with diameter 1.5 is 2013.15lb

<h3>The static equilibrium is given as:</h3>

F = P (Normal force)

Formula for moment at section

M = P(4 + 1.5/2)

= 4.75p

Solve for the cross sectional area

Area = $\frac{\pi d^{2} }{4}$

d = 1.5

$\frac{\pi *1.5^{2} }{4}$

= 1.767 inches²

<h3>Solve for inertia</h3>

$\frac{\pi *0.75^4}{4}$

= 0.2485inches⁴

Solve for the tensile force from here

$\frac{F}{A} +\frac{Mc}{I}$

30x10³ = $\frac{P}{1.767} +\frac{4.75p*0.75}{0.2485} \\\\$

30000 = 14.902 p

divide through by 14.902

2013.15 = P

The largest tensile force that can be applied to the cables given a rod with diameter 1.5 is 2013.15lb

What’s a pigtail when wiring

Levart [38]

Answer:

A pigtail when wiring is technique that is used in connecting a lot of wires together.

Explanation:

A pigtail is a wire that is short in length. It has two ends. One end has a connector while the other end has other wires connected to it.

Pigtail when wiring is the connection of more than one wire in a circuit to another device. Pigtail when wiring helps to extend the length of the wire in a circuit if the wire used it short).

Pigtail when wiring is a technique what helps to keep the circuit organised because it prevents the wires from getting tangled.
