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

The first term is a₁ = 2.
Each subsequent term is the reciprocal of the square of the preceding term.
2nd term:
a₂ = 1/2² = 1/4
3rd term:
a₃ = 1/(1/4)² = 1/(1/16) = 16
4th term:
a₄ = 1/16² = 1/256
5th term:
a₅ = 1/(1/256)² = 1/(1/65536) = 65536
The positive square root of the fifth term is
√(65536) = 256
