You’re an electrical engineer designing an alternator (the generator that charges a car’s battery). mechanical engineers specify a 10-cm-diameter rotating coil, and you determine that you can fit 250 turns in this coil. to charge a 12-v battery, you need a peak output of 14 v when the alternator is rotating at 1200 rpm. what do you specify for the alternator’s magnetic field?

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
