Answer:
a)True
Explanation:
While machining of ductile material and high feed and low cutting speed welding action take place between tool material and chip material this welding action is called built up edge. Built up edge action takes place due to high temperature.
To decrease the built up edge action
1. Increase the rake angle.
2. Increase the cutting speed
3. Decrease the feed rate
4. Use cutting fluid
Answer:
The correct option is d ( Neither A nor B)
Explanation:
Technician A made 2 mistakes in his statement.Firstly the tire is self supporting not self sealing.
Secondly, this tire does not provide permanent sealing of punctured area option a is incorrect.
This self-supporting tire after being affected with complete air leakage can temporarily bear the load of the car and avoid rolling over a distance of 80 km at a maximum speed of 55 mph. Here is what technician B suggested incorrectly as the tire after being.Here the technician B suggested incorrectly as the tire after being affected with puncture can not travel at any speed so option B is wrong
Since option a and b are incorrect and c is invalid.

The condensed Q formula may be used for operations in which the friction loss can be determined for a: 3, 4, or 5 inch hose.
<h3>What is a firehose friction loss?</h3>
A firehose friction loss can be defined as a measure of the effect of the resistance of water against the inner side of a firehose, which typically results in a pressure drop at the terminal end.
Generally, some of the factors that affect the resistance or friction in a firehose include:
Mathematically, the firehose friction loss can be calculated by using this formula:
FL = C × (Q/100)² × L/100.
