Week -2

Q1.Ans= For creating the model i use the solenoid coil because solenoid coil is work as the switching purpose when we give the supply to both the positive and negative terminal the coil get energized and create the magnetic field. in this coil i give the supply to that from battery source and also the common reference then the for obereving the the plunger movement i use the translational motion sensor.

As the condistion is given as the for 2sec observe the position of plunger i use the pluse generator for creating the signal and connect with the help of smulink to ps converter.

In the output i oberve with the help of scope i observe that the signal is vary for 2sec and after is come its initial position.

Q2= Thermistor in this challenge there are electromechniacal canvas are use for the perform the operaton

In that we problem we canot give the direct input to the given circuit for that purpose i have to create the signal according to the input condition according to it. after that.

in signal builder there is default value is in degree celcious but we have to convert it into the kelvin after that we give a finite output.

so taking the thermistor is in the circuit i have to give the input supply to them with the help of battery then its thermal port connection i have take the controlled temperature source for the connection.

Also connect the resister in series with the thermistor and connect the voltage sensor parallel to the resistor after that i take the switch there is 3 port in the switch which is one is connect with the constant value that means on another will be connect with the output of the voltage sensor and 3rd port is also connect to the constant value which is in off condition.

The switch threshold value which will be given on the condition on the input which is converted by degree celcious to kelvin.

Then output of the switch is connect to the controoled voltage source and output of the voltage source is connect with the dc motor for the rotation of fan. To analysis the Fan Rotation i take the ideal rotational motion sensor and its output will be connect with the scope with the help of ps to simulink converter.

In result shown in the scope fan is on only the temperature is above 25 degree celcious either it will be get off.
