D is correct. Hope this helped.
option c) The line segment AC is the diameter of circle F.
<u>Step-by-step explanation</u>:
- The 'diameter' is the line segment that passes through the center of the circle.
- In the circle shown, F is the center of the circle.
- The line segments EB and AC passes through the center point F.
- Therefore, both EB and AC are the diameters of the given circle.
- From the options given, option c) AC is the correct answer.
40 x 0.08875 = 3.55
40 + 3.55 = 43.55
the sum is $43.55
I think the Answer is 76 in^2
Hope this helps
Answer:
Step-by-step explanation:
Given:
elongation, x = 0.50 in
Force, f = 9000 lb
Young modulus, E = 10,000,000 psi
Maximum Stress, Sm = 30000 psi
Length, L = 16 ft
Converting ft to in,
12 in = 1 ft
=16 × 12 = 192 in
Young modulus, E = stress/strain
Stress = force/area, A
Strain = elongation, x/Length, L
E = f × L/A × E
1 × 10^7 = stress/(0.5/16)
= 26041.7 psi
Minimum stress = 26041.7 psi
Maximum stress = 30,000 psi
Stress = force/area
Area = 9000/26041.7
= 0.3456 in^2
Stress = force/area
Area = 9000/30000
= 0.3 in^2
Using minimum area of 0.3 in^2,
A = (pi/4)(d^2)
0.3 in^2 = (pi/4)(d^2)
d = 0.618 inches
diameter, d = 0.618 inches
