If feathers have a density of 0.500 lbs/ft^3, what volume in ft^3 will 8.0 lbs of feathers occupy?
OleMash [197]

Answer:

<em>The volume of the feathers in ft³ = 16 ft³</em>

Explanation:

Density: This can be defined as the ratio of mass of a body to the corresponding volume of that body. The S.I unit of Density is kg/m³

Mathematically it can be expressed as,

D = m/v ................................... Equation 1

making v the subject of the equation above,

v = m/D ............................. Equation 2

Where D = Density of the feathers, m = mass of the feathers, v = volume of the feathers.

Given: D = 0.50 lbs/ft³, m = 8.0 lbs.

Substituting into equation 2

v = 8/0.5

v = 16 ft³

<em>Thus the volume of the feathers in ft³ = 16 ft³</em>

An engineer is designing a spring to be placed at the bottom of an elevator shaft. If the elevator cable should happen to break
Anuta_ua [19.1K]

Answer:

k = 9876 N/m

Explanation:

As per energy conservation we know that

initial total gravitational potential energy = final spring potential energy

so we have

mg(h + x) = \frac{1}{2}kx^2

also we know that maximum acceleration will be 5.3 g

so it is given as

a = \frac{k}{m} x

so we have

x = \frac{ma}{k} = \frac{5.3 mg}{k}

mg(h + \frac{5.3 mg}{k}) = \frac{1}{2}k(\frac{5.3mg}{k})^2

mg(h + \frac{5.3 mg}{k}) = \frac{14.045(mg)^2}{k}

h + \frac{5.3mg}{k} = \frac{14.045 mg}{k}

h = \frac{8.745mg}{k}

k = \frac{8.745 (1439)(9.81)}{12.5}

k = 9876 N/m
