Answer:
0.867
Explanation:
The driver population factor ()can be estimated using the equation below:
The value of the heavy vehicle factor () is determined below:
The values of the = 2 and = 3 are gotten from the tables for the RVs, trucks and buses upgrades for passenger-car equivalents. Therefore:
= 1/[1+0.08(2-1)+0.06(3-1)] = 1/[1+0.08+0.12] = 1/1.2 = 0.833
Furthermore, the vp is taken as 2250 pc/(h*In) from the table of LOS criteria for lane freeway using the 15 minutes flow rate. Therefore:
= 3900/[0.8*3*0.833*2250] = 3900/4498.2 = 0.867
Answer:
G =67.74
Explanation:
Given that
length l=2.4 m
Outside diameter= 16 cm
Inside diameter= 15 cm
Speed N =900 RPM
We know that
Where r is the radius V is the velocity.
So mean radius
r = 7.5 cm
We know that
V=ω x r
V= 94.24 x 0.075 m/s
V= 7.06 m/s
G =67.74
Answer:
The appropriate solution is "1481.76 N".
Explanation:
According to the question,
Mass,
m = 540 kg
Coefficient of static friction,
= 0.28
Now,
The applied force will be:
⇒
By substituting the values, we get
Answer:
An adaptation is the physical or behavioural characteristic of an organism that helps an organism to survive better in the surrounding environment.
In engineering im assuming that an adaptation would just be an improved tool of sorts
