Answer:

900 cm

Step-by-step explanation:

1 : 50

We need the first number to be 18 so multiply by 18

1:18 : 50*18

18 cm : 900 cm

Using the given information, give the vertex form equation of each parabola.
elena-s [515]

Answer:

The answer to your question is   y = 2(x + 8)²

Step-by-step explanation:

This is a vertical parabola that opens upwards

The distance from the vertex to the directrix is 1/8 so p = 1/8.

Equation

                 (x - h)² = 4p(y - k)

h = -7

k = 0

p = 1/8

Substitution

              (x + 8)² = 4(1/8)(y - 0)

Vertex form equation

              (x + 8)² = 1/2(y)

              y = 2(x + 8)²

              x² + 16x + 64 = 1/2y

              2x² + 32x + 128 = y

General equation

              2x² + 32x - y + 128 = 0

Determine the moment m that will produce a maximum stress of 70 mpa on the cross-section
gogolik [260]

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

More about the bending stress link is given below.
