Answer:
W = 2695.14 lb
Explanation:
given,
side of cube = 3 ft
density of the cube = 3.1 slugs/ft³
we know,
mass = density x volume
volume = 3³ = 27 ft³
mass = 3.1 x 27
m = 83.7 slugs.
weight calculation
converting mass from slug to pound
weight of 1 slug is equal to 32.2 lb
now,
weight of the cube is equal to
W = 83.7 slugs x 32.2 lb/slug
W = 2695.14 lb
hence, weight is equal to W = 2695.14 lb

Quality of exhaust steam = 0.959
Explanation:
<u>Explanation:</u>
Determine the weight of footing
Where is the weight of footing, γ is the unit weight of concrete, L is the length of footing is the width of footing, and D is the depth of footing
Substitute for γ in the equation
Therefore, the weight of the footing is 35.4 kN
Determine the initial vertical effective stress.
Here, is initial vertical stress at a depth below ground surface γ is the unit weight of soil, D is depth and u is pore water pressure.
Substitute for u in the equation
Therefore, the initial vertical stress is 36 kPa
Determine the vertical effective stress.
Here, is initial vertical stress at a depth below ground surface γ is the unit weight of soil, D is depth and u is pore water pressure.
Substitute in the equation.
Therefore, the vertical stress at a depth below the ground surface is
9 kPa
Determine the influence factor at the midpoint of soil layer,
Here is the influence factor at the midpoint of soil layer
is initial vertical stress,
is vertical effective stress, and
is bearing pressure
Substitute in the equation
Therefore the influence factor at the midpoint of the soil layer is 0.693
