The question is incomplete as the data set are missing. However, I'll use the following data to answer your question:
<em>5,12,3,18,6,8,2,10
</em>
Start by calculating the mean:
Standard deviation is calculated using:
This gives:
<em>Apply the above steps in the original question, then you will get your correct answer.</em>
Answer:
Roll force, F = 5.6 MN
Explanation:
Sheet width, b = 0.5 m
Roll contact length,
Strength coefficient,
Thickness, h = 11 mm
Since the sheet of metal is cold worked by 40%, the reduction in thickness will be:
Δh = 40% * 11 = 0.4 * 11 = 4.4 mm
Strain, e = (Δh)/h
e = 4.4/11 = 0.4
The roll force is calculated by the formula:
Substituting the value of , , and b into the formula for the roll force:
Answer:
(b) an equivalent AC current source in parallel with an equivalent reactance
Explanation:
The Norton AC equivalent circuit is composed of a Norton current service as the source, and it is in parallel to a Norton resistor, which can be valid for any type of load. Norton equivalent circuit is valid for a single frequency in AC circuits.
Since this traffic flow has a jam density of 122 veh/km, the maximum flow is equal to 3,599 veh/hr.
<u>Given the following data:</u>
- Jam density = 122 veh/km.
<h3>How to calculate the
maximum flow.</h3>
According to Greenshield Model, maximum flow is given by this formula:
<u>Where:</u>
- is the free flow speed.
- is the Jam density.
In order to calculate the free flow speed, we would use this formula:
Substituting the parameters into the model, we have:
Max flow = 3,599 veh/hr.
