Answer:
thread depth = 2.5 mm
thread width = 2.5 mm
mean diameter = 27.5 mm
root diameter = 25 mm
lead of screw = 5 mm
Explanation:
given data
power screw diameter D = 30 mm
thread pitch P = 5 mm
solution
First, we get here thread depth fr square thread
thread depth = 
......................1
thread depth = 
thread depth = 2.5 mm
and
thread width for square thread
thread width = ......................2
thread width =
thread width = 2.5 mm
and
mean diameter is
mean diameter = D - ................3
mean diameter = 30 -
mean diameter = 27.5 mm
and
root diameter is
root diameter = D - P ....................4
root diameter = 30 - 5
root diameter = 25 mm
and
lead of screw for single thread so n = 1
so lead of screw = 1 × 5
lead of screw = 5 mm
Answer:
527
Explanation:
Data provided in the question:
Number of crashes per year at the intersection = 13
The 4 legs of the intersection had 2-way ADT values :
9671, 2893, 9506 and 2611 vehicles last year.
Now,
ADT = 9671 + 2893 + 9506 + 2611
= 24,681 vehicles
Rate per Million Entering Vehicles, (RMEV )
= [ ( crashes per year ) ÷ ( Approach ADT per year ) ] × 10⁶
or
RMEV = [ ( 13 ) ÷ (24,681) ] × 10⁶3
or
RMEV = 526.721 ≈ 527
