Calculate KI for a rectangular bar containing an edge crack loaded in three-point bending where P=35.0 kN, W=50.8 mm, B=25 mm, a

Katyanochek1 [597]

Answer:

$K_{I}=5.21 MPa\sqrt{m}$

Explanation:

given data

Load P = 35 kN

Width of bar W = 50.8 mm

Breadth of bar B = 25 mm

Ratio of crack length to width α = a/W = 0.2

solution

we get here KI for a rectangular bar that is express as

$K_{I} = \frac{6P}{BW}Y\sqrt{\pi a}$ ................................1

here Y is the geometrical function

Y = $\frac{1.12+\alpha (3.43\alpha -1.89)}{1-0.55\alpha}$

Y = $\frac{1.12+0.2(3.43\times 0.2-1.89)}{1-0.55\times 0.2}$

Y = $\frac{0.8792}{0.89}$

Y = 0.9878

so put here value in equation 1

$K_{I} = \frac{6\times 35\times 10^{3}}{0.025\times 0.0508}\times 0.9878\times \sqrt{3.1415\times (0.2\times 0.0508)}$

$K_{I} = 165354.33\times 10^{3}\times 0.9878\times 0.0319$

$K_{I}$ = 5210.45 × 10³ $Pa\sqrt{m}$

$K_{I}$ = 5.21 MPa $\sqrt{m}$

Answer:

Geological engineers can help determine if the soil and structural stability in the building's location are satisfactory.

Explanation:

Geologic Engineering refers to a job which applies geology to engineering. This type of job focuses on the investigation of sites in response to soil, rock and groundwater. They help design the major structures for engineering works, thus, it is also their role to know whether the building's soil and structural stability are satisfactory. They determine how much of the structure is a safe load for the soil it is standing upon. They also test the strength of both rock and soil at different depths. This will help them know whether the location will be suitable for the skyscraper.

Dimas [21]

Answer:

The research and development plays an important role in the maintenance engineering is that it basically improve the equipment maintainability and reliability.

According to the requirement, the system and the equipment needs to be maintain in the maintenance engineering.

The research and the development basically provide the products and services and also improve the existing products and services of the system in the maintenance engineering.
