Week -2

1.

Whole door bell arrangement is done in such a way so when pulse generator is given 2 sec to open and close the switch. So when switch is closed , solenoid recieves electric power from battery which inturns moves plunger from R to C thus hits the bell and produces sound.

Here pulse generator is used to produce square signal with 2 sec interval. switch is controlled by external physical signal and when signal is higher than the threshold value sitch closes.Solenoid is connected with both electrical and mechanical components thus a mechanical and electrical refernces are connected respectively.Ps- simulink and simulink-ps converter are used to convert signal from simscape library to other and vice versa.

As per the fan conditions for first 10 sec temperature will be 293 K and when from 11 sec it hits 300K it goes above threshold value of 298K and Fan turns ON. After 30 sec temp is 296K which is below threshold value and fan turns off.
