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
If two vehicles arrive at an uncontrolled intersection almost simultaneously, the driver of the car that arrived at the intersection last must give the right of way. The driver on the left has the right of way if you both arrive at the intersection at the same moment.
Which driver should yield at an uncontrolled T-intersection?
The driver of the car turning must give way to all oncoming cross traffic when two cars are approaching an uncontrolled "T" crossroads. You need to stop and give way to vehicles and pedestrians while entering a public road from a driveway or private road.
What is right of way?
When two vehicles or pedestrians are approaching from opposite directions, moving at a speed, and close enough to create a collision, one has the right to move forward legally before the other, unless the other gives way.

Answer:
119.35 mm
Explanation:
Given:
Inside diameter, d = 100 mm
Tensile load, P = 400 kN
Stress = 120 MPa
let the outside diameter be 'D'
Now,
Stress is given as:
stress = Load × Area
also,
Area of hollow pipe = 
or
Area of hollow pipe = 
thus,
400 × 10³ N = 120 ×
or
D² = tex]\frac{400\times10^3+30\pi\times10^4}{30\pi}[/tex]
or
D = 119.35 mm
Answer:
an importer
Explanation:
Jason's petrochems depends on imported intermediates for its production/processing. From the question, the firm imports chemical intermediates, processes them in its laboratories before selling them. It also uses the intermediates to produce various fertilizers and solvents. Essentially its feed stocks ( inputs) are wholly imported from different countries. Hence the firm is an import dependent petrochemical complex.
