Answer:

small forewing

<u>pro</u> : Can be used in place of tail plane configuration

<u>con</u> : Can be very complex and difficult to use

Explanation:

A canard is generally used to provide some form of stability to an unstable or semi stable system.

An example of a Canard is a small forewing placed in an aircraft that will help stabilize the aircraft when in motion( in air ). because an airplane is generally an unstable system on its own

A gas cylinder is connected to a manometer that contains water. The other end of the manometer is open to the atmosphere, which
horrorfan [7]

Answer: the absolute static pressure in the gas cylinder is 82.23596 kPa

Explanation:

Given that;

patm = 79 kPa, h = 13 in of H₂O,

A sketch of the problem is uploaded along this answer.

Now

pA = patm + 13 in of H₂O ( h × density × g )

pA= 79 + (13 × 0.0254 × 9.8 × 1000/1000)

pA = 82.23596 kPa

the absolute static pressure in the gas cylinder is 82.23596 kPa

A soil specimen was tested to have a moisture content of 32%, a void ratio of 0.95, and a specific gravity of soil solids of 2.7
belka [17]

Answer:

a. 0.9263

b. 0.4872

c. 13.83kN/m^{3}

Explanation:

moisture content (ω) = 0.32

void ratio (e) = 0.95

specific gravity (G_{s}) = 2.75

the degree of satruation (S) = \frac{w . G_{s} }{e} =0.32×2.75/0.95 = 0.9263

b. porosity (n) = \frac{e}{e + 1} = 0.95/(0.95 + 1)= 0.4872

c. dry unit weight (γ_{d}) = \frac{G_{s} . V_{w} }{1 + e}

taking specific unit weight of water (V_{w})= 9.81kN/m^{3}

γ_{d} = 2.75 × 1000/(1 + 0.95) = 13.83kN/m^{3}
