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)

Assume similar data for the motion of the blood in your aorta. estimate how many beats of the heart it will take the blood to get from your heart to your brain. (assume that the distance from your heart to your brain is 30 cm)

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
