Material with hardness of 220 Vickers is harder than material with a hardness of 180 Vickers. a)-True b)- False

Engineering
1 answer:
PSYCHO15rus [73]3 years ago
6 0

Answer:

Correct option a) True.

Explanation:

It is true since the Vickers hardness value refers to the force applied in a 136 ° diamond tip penetrator divided by the surface of the groove produced in the material, the lower the impression made on this greater the value will be end of the Vickers measurement and greater its hardness.

The equation to determine the Vickers hardness value will be:

Hv= ((1.854 × P)/(d²))  (kg/mm²)

Therefore a value of 220 Vickers refers to a harder material than another value of 180 Vickers.

How does a motion sensor work?
Ahat [919]

Answer:

A motion sensor uses one or multiple technologies to detect movement in an area. When a sensor detects motion, it sends a signal to your security systems control panel, which connects to your monitoring panel system. This alerts you and the monitoring center to a potential threat in your home.

Which of these analysis methods describes neural computing? a. historical if-then-else cases are used to recognize patterns O b.
Lera25 [3.4K]

Historical data is examined for patterns that are then used to make predictions is one of the analysis methods that describe neural computing

What is neural computing?

A neural network is an artificial intelligence technique that instructs computers to analyze data in a manner modeled after the human brain. It is a kind of artificial intelligence technique known as deep learning that makes use of interconnected neurons or nodes in a layered structure to mimic the human brain.

Historical data is nothing but the existing network data which is stored for the predicting in future

In the context of neural networks, the word "pattern" refers to a collection of activations over a group of units (neurons).

Hence to conclude neural netwoks almost describes the patterns

Anon25 [30]

Answer:

The flexural strength of a specimen is = 78.3 M pa

Explanation:

Given data

Height = depth = 5 mm

Width = 10 mm

Length L = 45 mm

Load = 290 N

The flexural strength of a specimen is given by

\sigma = \frac{3 F L}{2 bd^{2} }

\sigma = \frac{3(290)(45)}{2 (10)(5)^{2} }

\sigma = 78.3 M pa

Therefore the flexural strength of a specimen is = 78.3 M pa
