Answer:
Option B is the answer – Oligopoly
Explanation:
Usually, there are not set limit to the number of firms that can come together to form the oligopolistic market structure but the number must be low so that one firm can significantly have an influence on the other. This form of market arrangement can been seen in most part of the world and the common industries dominated by oligopolies are; Cable Television services, Oil and Gas, airlines, etc
Answer:
The stresses in steel and the copper are, 128 ksi and 72.44 ksi, respectively.
Explanation:
In this case, we need to calculate the area of both portions separately.
Thus, we know that:
Inner Radius = Rin = (1/2 in)/2 = 0.25 in
Outer Radius = Rout = (5/8 in)/2 = 0.3125 in
FOR STEEL CORE:
Area of steel core = As = π(Rin)² = π(0.25 in)² = 0.0625 in²
Hence, the stress will be:
σs = Force / As
σs = 8000 lb/ 0.0625 in²
<u>σs = 128 ksi</u>
FOR COPPER:
Area of copper = Ac = π[(Rout)² - (Rin)²]
Ac = π[(0.3125 in)² - (0.25 in)²] = 0.11044 in²
Hence, the stress will be:
σc = Force / Ac
σc = 8000 lb/ 0.11044 in²
<u>σc = 72.44 ksi</u>
