A150 mm long normalized 1045 steel shaft is turned down from a diameter of 100 mm to 90 mm in a single pass. the side cutting edge angle σ is 0°, the cutting speed v is 135 m/min, and the feed per revolution fr is 0.22 mm. determine (a) the chip area a [mm2], (b) the material removal rate q [cm3/min], (c) the tangential component of the cutting force ft [kn], (d) the power needed to drive the turning operation p [kw], and (e) the machining time t [min].

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

The two required components for a generator

An electron is ejected into a horizontal uniform e⃗ field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the e⃗ field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.
