If your odometer reading is 20000 (miles) and your new tires have a circumference of 101.5.  How far have you really traveled if you factory tires were only 75 inches around?

I need help with number 11 and 14. Please see markedup image attached. 11. On the part attached, specify a geometric control to make the left surface in the front view perpendicular to the bottom surface within .005 total. 14. On the part attached, there is no perpendicularity requirement specified between the right surface and bottom surface. What perpendicularity is implied?

Two cylinders act right after one another. Each cylinder is metered, and some actions are slow, and there is a dwell between some actions. What is the minimum flow rate required (CFM) to operate this cylinders? (enter answer with 2 decimal places) Sequence of operations: Cyl. A extends with metering (takes 1.5 second) Dwell time for 2 seconds for part machining Cyl. B extend and retracts without metering (2 second) Dwell time for 10 seconds while an electric mixer is operated Cyl. A retracts quicky with no metering (0.5 seconds) Dwell time for 5 seconds while a part is placed before next cycle   Assuming the displacements of the cylinders are: Cyl. A DE = 65 in3 Cyl. A DR = 62 in3 Cyl. B DE = 44 in3 Cyl. B DR = 41 in3

The normal component of acceleration an represents the time rate of change in the magnitude of velocity.   C. The normal acceleration an is not always toward the center of curvature.   D. The tangential component of acceleration at represents the time rate of change in the magnitude of velocity.

18 The layout foreman is using the transit to turn an angle to the left of 45° 20' 30". The transit being used only gives readings in the clockwise direction. Subtracting from 360°, what reading will the instrument be turned to? be

Which statement is true in the case of the term "Range". O Is closely related to accuracy and define the minimum and maximum values an instrument is designed to measure. O Is closely related to accuracy and output reading of an instrument is linearly proportional to the quantity being measured. O Is not related to accuracy and define the maximum error of the measuring instrument during measurement process. The minimum and maximum values the instrument is designed to measure

When using a Vernier motion sensor to record the position of a cart on a track, the sensor itself:  Select one: a. may not be properly aligned, in which case you should call the TA b. is always perfectly aligned and not adjustable c. requires you to test it's alignment before attempting to take data

Investigate, and select appropriate sensors for the specified system.

Basic Conversions A solid flat disk is rotating in the counter-clockwise (or positive) direction. There is an object (small black dot) on the disk, rotating with the disk. The object is a distance 1.30 meters from the axis of rotation (the center of the disk). It had an angular velocity of 4.00 radians / second at the initial position of 0 Radians (see black line on image). After 1.57 seconds, it has an angular velocity of 7.00 radians / second at the position shown in the picture. O Radians What is the tangential linear acceleration as it has moved from the 0 position to the current position? Your answer should have the following: 2 Decimal Places Correct SI Units Appropriate Signs for Vector quantity answers Answers must be in the following format: Written out and NOT in scientific notation Acceptable: 278.40 Not Acceptable: 2.784 x 102 Your Answer: Answer units

Describe at least two methods of checking the operation of Hall-effect sensors used in engine management systems. (40 - 60 words)

When the variable being measured is at its minimum condition during the calibration procedure, a __________ adjustment is made if the reading is inaccurate. Group of answer choices span range width zero       Calibration should not be performed __________. Group of answer choices None of the above. before new instrument installations after repair after extended shutdown       A 4-20mA transmitter that is properly calibrated will produce a signal of _____ mA when the measured variable is at the exact midpoint of its range. Group of answer choices 9 15 20 12       When a calibration procedure is performed on the level of a liquid in a storage tank, it must be completely empty when making the zero adjustment. Group of answer choices True False

A method to measure angular velocity is to use a proximity sensor that generates a pulse when a metal item is within the sensor’s detection range.A wheel is attached to an engine’s crankshaft that has a total 65 teeth. Each tooth is within the sensor’s detection range, however, each gap between the teeth is not within the sensor’s detection range. The engine is running at some angular speed. Determine the engine’s speed (in RPM) if a proximity sensor generates a frequency of 4,256 Hz

On the part shown, specify a geometric control to make the left surface in the front view perpendicular to the bottom surface within .005 total, and what would the the flatness on the left surface of the part above be? Can a datum or feature modifier be applied to this feature control frame? why or why not?

How would you answer this question

On a rotor wing NVG flight, your aircrew is circling (clockwise) a target area illuminated by an aerial parachute flare. The door gunner on the side of the aircraft opposite the flare (left) notices the ground getting closer and calls, "knock it off". What visual illusion just occurred and which aircrew member(s) were affected? OA. Moth effect; pilot, copilot, right door gunner OB. False horizon; left door gunner OC. Lean-on-the-sun illusion; all crew members O D. G-excess; left door gunner
