Amagnesium alloy bar 6 in. in diameter is being turned on a lathe at a depth of cut d = 0.050 in. the lathe is equipped with a 10-hp electric motor and has a mechanical efficiency of 80%. the spindle speed is 500 rpm. estimate the maximum feed that can be used before the lathe begins to stall.(0.45 w-s/mm^3 value of specific power for magnesium alloy)

We all use gps today, even if we don't drive yet. i bet you have been in the car with a parent and they have asked you to get out your phone to find a specific location. in your car, on the phone, you are using a very sophisticated technology. gps satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. gps receivers take this information and use trilateration to calculate the user's exact location. essentially, the gps receiver compares the time a signal was transmitted by a satellite with the time it was received. the time difference tells the gps receiver how far away the satellite is. now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map. what type of signal is utilized by the gps satellite?
