Vehicles arrive at a single toll booth beginning at 8:00 A.M. They arrive and depart according to a uniform deterministic distri
bution. However, the toll booth does not open until 8:10 A.M. The average arrival rate is 8 veh/min, and the average departure rate is 10 veh/min. Assuming D/D/1 queuing, when does the initial queue clear and what are the total delay, the average delay per vehicle, longest queue length (in vehicles), and the wait time of the 100th vehicle to arrive (assuming first-in-first-out)?

Answer:
initial diameter of the sample is 2.95 mm
Explanation:
given data
yield load = 2100 N
maximum load = 3400 N
failure load = 2350 N
ultimate engineering stress = 497.4 MPa = 497 × N/m²
to find out
What was the initial diameter of the sample in mm
solution
we will apply here ultimate engineering stress formula that is express as
ultimate engineering stress = ...............1
here A is area and P max is maximum load applied
so area =
here d is initial diameter
so put all value in equation 1
497 × =
solve it we get d
d = 2.95 × m
so initial diameter of the sample is 2.95 mm
