Brake system
Explanation: the engine doesn’t need to be running to make the brake system work the brake system it’s independent
Answer
given,
6 lanes divided highway 3 lanes in each direction
rolling terrain
lane width = 10'
shoulder on right = 5'
PHF = 0.9
shoulder on the left direction = 3'
peak hour volume = 3500 veh/hr
large truck = 7 %
tractor trailer = 3 %
speed = 55 mi/h
LOS is determined based on V p
10' lane weight ; f_{Lw}=6.6 mi/h
5' on right ; f_{Lc} = 0.4 mi/hr
3' on left ; no adjustment
3 lanes in each direction f n = 3 mi/h



= 0.877

= 1,555 veh/hr/lane

= (55 + 5) - 6.6 - 0.4 -3 -0
= 50 mi/h


level of service is D using speed flow curves and LOS for basic free moving of vehicle
Answer:
The circulation around the cylinder is 0.163 
Explanation:
Given :
Velocity of spinning cylinder

Sea level density

Sea level span

Lift per unit circulation is given by,

Where
circulation around cylinder



Therefore, the circulation around the cylinder is 0.163 
Can I get a picture? Of the question so I can understand it more?
Answer:
A. optical isolation
Explanation:
well I can't really give a good explanation because I also saw the same question in my exams and option A was the correct answer
