Calculate the torque produced by a motor that has 500 windings across a 30cm diameter rotating core. The core is 0.6 M long inside a 50 tesla magnetic field. The resistance of the wire is 30 ohms when 12 volts are applied.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

You are making beer. the first step is filling the glass carboy with the liquid wort. the internal diameter of the carboy is 15 in., and you wish to fill it up to a depth of 2 ft. if your wort is drawn from the kettle using a siphon process that flows at 3 gpm, how long will it take to fill?
