Answer:
Explanation:
Given Preception time = 1.0 sec
Deceleration rate = 11 ft /sec2
Interpretation rate as = 3words /sec
The board consists of “WORK ZONE: 20 MPH SPEED ZONE”
Then Interpretation time = 2.0 sec
Decision time = 0.5 sec
Assume that the vehicle was traveling with 65mph
Perception Time
So, if you’re driving at 65 mph, your vehicle will travel 71 feet before you realize you need to start braking.
Reaction Distance
At 65 mph, that’s another 71 feet traveled.
Braking Distance
At 65 mph, it takes an additional 5.5 seconds or about 525 feet of actual brake application to stop your vehicle.
Stopping Distance
To determine the stopping distance, you calculate: Perception Distance (71 feet) + Reaction Distance (71 feet) + Braking Distance (525 feet) = Stopping Distance (667 feet)
Then to reduce the speed it takes 7.0 secs

Answer:
The engineering design process
Explanation:
Answer:
The correct answer is A : Orientation dependence of normal and shear stresses at a point in mechanical members
Explanation:
Since we know that in a general element of any loaded object the normal and shearing stresses vary in the whole body which can be mathematically represented as
And
Mohr's circle is the graphical representation of the variation represented by the above 2 formulae in the general oriented element of a body that is under stresses.
The Mohr circle is graphically displayed in the attached figure.
