Answer:
C. 81/256
Step-by-step explanation:
You have to divide it then raise it to the negative power.
If acr AC is one fifth of the whole circle, angle AOC is 1/5 of 360,
angle ABC is half of angle AOC, so the m∠ABC=36
The moment M that will produce a maximum stress of 70 MPa on the cross-section of 177.3 will be 13.533 kN-m.
<h3>What is bending stress?</h3>
Bending stress is the typical stress that an item experiences when it is exposed to a heavy load at a specific spot, causing it to bent and fatigue.
The moment of inertia above the neutral axis will be
Iₓₓ = 99 x 84.7³/3 - (99 - 12 x 3) (84.7 - 12)³/3
Iₓₓ = 11983247 mm⁴
The moment of inertia below the neutral axis will be
Iₓₓ = 2 x 12 x (87 - 84.7)³/3 + 12 x 177.3³/3
Iₓₓ = 22294005 mm⁴
Then the moment of inertia about the neutral axis will be
Iₓₓ = + 11983247 + 22294005
Iₓₓ = 34277252 mm⁴
Then for maximum bending stress, we have
M = σ x Iₓₓ / y(max)
We have
σ = 70 MPa
Iₓₓ = 34277252 mm⁴
y(max) = 177.3
Then we have
M = 70 x 34277252 / 177.3
M = 13.533 kN-m

Answer:
The choose D (2, –1)
2x-3y=4 —> 3y=2X-4 —> y= 2/3x – 4/3
y=mx+b —> So ; m= 2/3 , b= - 4/3
y-intercept :(0, -4/3)
0=2/3x –4/3 —> 2/3x = 4/3 —> X=2
x-intercept ; (2,0)
By drawing a straight line from point 2 on the x-axis and point -4/3 on the y-axis, the points that are on the axis have been extracted, but the point (2,-1) is not on the axis . :)
I hope it helped you ^_^
B. 16.. because its in the middle
