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

<em>Answer:</em>
<em>The right side of the equation is only a different way of writing the left side, so any value of x will solve this equation.
</em>
<em>
</em>
<em>The equation −
2
( x + 3 ) = −
2
x − 6 does not have any specific solutions for the simple reason that the left and rigth sides are two representations of the same equation.
</em>
<em>
We have −
2
( x + 3 ) means that each term inside the parenthesis should be multiplied with −
2
, i.e.</em>
<em>
−
2
( x + 3
) = −
2 ⋅ x − 2 ⋅ ( + 3
) = −
2
x − 6
</em>
<em>
</em>
<em>Which is exactly what the right side says.
</em>
<em>
</em>
<em>Any value of x will, therefore, fulfill this equation.</em>
Answer:
4.2 and 4.3
Step-by-step explanation:
Answer: 
Step-by-step explanation:
By the negative exponent rule, you have that:
By the exponents properties, you know that:
Therefore, you can rewrite the left side of the equation has following:
Descompose 32 and 8 into its prime factors:
Rewrite:
Then:
As the base are equal, then:
Solve for x:
