A 2.5 m wide rough continuous foundation is placed in the ground at 1 m depth. There is bedrock present at 1 m depth below the b

ottom of the foundation. The soil properties are c9 5 10.0 kN/m2 , f9 5 258, and g 5 18.0 kN/m3 . Determine the ultimate bearing capacity of the foundation.

Answer:

45.873 KN/mL is the ultimate bearing capacity of the foundation.

Explanation:

C' = 10.0 kN/m²,  Ф' = 25,  r = 18 kN/m²

ration of Df/B ≤ 1 ,   Df ≤ B (1 ≤ 2.5m)

It is a shallow foundation

∴ Ultimate bearing Capacity

qu = C'N_c + rD_F.N_q + \frac{1}{2}BrN_r

NФ = tan²(45 + Ф/2)

      = tan²(45 - 25/2)

      = 0.41

Nq = NФ×e^(πtanФ') = 0.41e^(πtan25)

     = 1.756

Nr = 1.8tanФ(Nq - 1) = 1.8tan25(1.756 - 1)

    = 0.634

Nc = 1.621

putting the above values in equation.

qu = 45.873 KN/mL

Determine the following parameters for the water having quality x=0.7 at 200 kPa:
ra1l [238]

Solution :

Given :

Water have quality x = 0.7 (dryness fraction) at around pressure of 200 kPa

The phase diagram is provided below.

a). The phase is a standard mixture.

b). At pressure, p = 200 kPa, T = $T_{saturated}$

   Temperature = 120.21°C

c). Specific volume

  $v_{f}= 0.001061, \ \ v_g=0.88578 \ m^3/kg$

  $v_x=v_f+x(v_g-v_f)$

       $=0.001061+0.7(0.88578-0.001061)$

       $=0.62036 \ m^3/kg$

d). Specific energy (u_x)

    $u_f=504.5 \ kJ/kg, \ \ u_{fg}=2024.6 \ kJ/kg$

   $u_x=504.5 + 0.7(2024.6)$

         $=1921.72 \ kJ/kg$

e). Specific enthalpy $(h_x)$

   At $h_f = 504.71, \ \ h_{fg} = 2201.6$

   h_x=504.71+(0.7\times 2201.6)

        $= 2045.83 \ kJ/kg$

f). Enthalpy at m = 0.5 kg

  $H=mh_x$

       $= 0.5 \times 2045.83$

       = 1022.91 kJ

A steel bar 100 mm (4.0 in.) long and having a square cross section 20 mm (0.8 in.) on an edge is pulled intension with a load o
grigory [225]

Answer:

The elastic modulus of the steel is 139062.5 N/in^2

Explanation:

Elastic modulus = stress ÷ strain

Load = 89,000 N

Area of square cross section of the steel bar = (0.8 in)^2 = 0.64 in^2

Stress = load/area = 89,000/0.64 = 139.0625 N/in^2

Length of steel bar = 4 in

Extension = 4×10^-3 in

Strain = extension/length = 4×10^-3/4 = 1×10^-3

Elastic modulus = 139.0625 N/in^2 ÷ 1×10^-3 = 139062.5 N/in^2

Getting the bottom of your feet burned when walking on hot sand is due to what form of energy transmission? group of answer choi
Scilla [17]

Getting the bottom of your feet burned when walking on hot sand is due to a form of energy transmission known as conduction.

<h3>The types of energy transmission.</h3>

In Science, there are three (3) main types of energy transmission and these include the following:

  • Convection
  • Radiation
  • Conduction

In this scenario, we can infer and logically conclude that burning the bottom of your feet when walking on hot sand is primarily due to a form of energy transmission known as conduction because it involves the transfer of thermal energy (heat) due to the movement of particles.
