In a processing plant, jars on a conveyer belt are cleaned out with a high-pressure air jet just prior to being filled (Figure Below). When a jar approaches the cleaning station, it activates a switch (with both NO and NC contacts). The conveyer belt stops for 10 s while the air jet is on; then the conveyer belt starts, and the jar moves along. Draw a ladder logic diagram to control this process.
One reason that the maximum electric field is important is because of the possibility of impact ionization, which may be desired or undesired in a particular application. The process of impact ionization is dependent on the electric field
a 60-kHz sinusoidal signal is applied to an amplifier with a gain of k=2. the circuit is built with an lm741 opamp with power supplies +-13V. find the largest amplitude the signal may have before it is limited by slew rate constraints.
When the starter motor, which draws 90A, is running the terminal voltage drops to 11V. What is the internal resistance of the battery What percentage of the chemical power is delivered to the starter motor
A plane circular disk of radius 0.25m rotates at a speed of 200 rad/s about an axis through the center of the disk perpendicular to the plane of the disk. There is a uniform magnetic flux B = 1 Tesla parallel to the axis of rotation.
A series-connected dc motor has RF+RA = .6 ohmns and draws IA = 40 A from the dc source voltage VT = 220 V, while running at 900 rpm. What is the speed for IA = 20 A Assume a linear relationship between IA and phi.
