Answer:
a) 0.2099
b) 46.5 MPa
c) 233765 N
d) 3896 W
Explanation:
a)
r = (A'' - A') / A'', where
A'' = 1/4 * π * D''²
A'' = 1/4 * 3.142 * 90²
A'' = 6362.55 mm²
D' = D'' - d = 90 - 10 = 80 mm
A' = 1/4 * π * D'²
A' = 1/4 * 3.142 * 80²
A' = 5027.2 mm²
r = (A'' - A') / A'
r = (6362.55 - 5027.2) / 6362.55
r = 1335 / 6362.55
r = 0.2099
b)
Draw stress = σd
Y' = k = 105 MPa
Φ = 0.88 + 0.12(D/Lc), where
D = 0.5 (90 + 80) = 85 mm
Lc = 0.5 [(90 - 80)/sin 18] = 16.18 mm
Φ = 0.88 + 0.12(85/16.18) = 1.51
σd = Y' * (1 + μ/tan α) * Φ * In(A''/A')
σd = 105 * (1 + 0.08/tan18) * 1.51 * In(6362.55/5027.2)
σd = 105 * 1.246 * 1.51 * 0.2355
σd = 46.5 MPa
c)
F = A' * σd
F = 5027.2 * 46.5
F = 233764.8 N
d)
P = 233764.8 (1 m/min)
P = 233764.8 Nm/min
P = 3896.08 Nm/s
P = 3896.08 W
The three architectural structures, natural or man made, that have withstood the test of time. describe the geometric shapes that they represent or contain are statues.
<h3>How are geometric shapes utilized in architecture?</h3>
Architects use geometry to take a look at and divide areas in addition to draft specified construction plans. Builders and engineers depend upon geometric concepts to create systems safely. Designers practice geometry (in conjunction with color and scale) to make the aesthetically appealing areas inside. Applying geometry in the layout is unavoidable.
Man-Made systems can consist of seawalls, breakwaters, harbor walls, pontoons and piers, to say a few. These may be crafted from a whole lot of substances now no longer constrained to wood, concrete, or metal, in addition to herbal rock that has been installed vicinity as a sea defence.

Answer: The black diamonds which appear every 19 3/16” on metal tape measures are for spacing I-beam “timbers”.
Explanation:
Answer:
Applied pressure on piston (P) = 50 psi. We know that work done is given by W = Force x displacement. S Force = Pressure x Areas > W = ( PXA ) X L W = PX ( AL ) W = PX AV = 50x 43.7088. W= 2185.
