Answer:
Explanation:
If the question is: Determine the banking angle θ
We have the forces involved on the figure attached.
For this case we know that the weight is given by:
And for this case the centripetal acceleration would be given by:
If we analyze the sum of forces on x and y we have:
And if we solve for the force we got:
If we solve for the normal force we got:
In order to find the banking angle we use the fact that F =0
The velocity on this case is 120 mi/h if we convert this into ft/ s we got:
And then we have this:
Answer:
I hope it is correct.....
Answer:
Option (d) 2 min/veh
Explanation:
Data provided in the question:
Average time required = 60 seconds
Therefore,
The maximum capacity that can be accommodated on the system, μ = 60 veh/hr
Average Arrival rate, λ = 30 vehicles per hour
Now,
The average time spent by the vehicle is given as
⇒
thus,
on substituting the respective values, we get
Average time spent by the vehicle =
or
Average time spent by the vehicle =
or
Average time spent by the vehicle =
or
Average time spent by the vehicle = hr/veh
or
Average time spent by the vehicle = min/veh
[ 1 hour = 60 minutes]
thus,
Average time spent by the vehicle = 2 min/veh
Hence,
Option (d) 2 min/veh
