If an airplane door has an area of 4032 in^2 and the pressure inside the plane is 14 psia (absolute), What is the force on the door when the plane flies at an altitude where the pressure is 2 psia?

Thanks I really appreciate all the help :)

So C is 23.3V - 11 V = 12.3 V and D would be 12.3V - .3V = 12V :)

So at C would be 23.3V + 11 V = 34.3 V with respect to ground?

Wait can you show me an example with either point A or B. I am not sure if I fully get what you meant.

ok fair enough but what about the voltages ( A,B,C and D) across the different points or is it the same for the voltage drop across R? Thanks again for all the help

ok well the voltage for the resistor is the Vcc added to the silicon diode. It is in forward basis, so its 12-.7 and then past the resistor into the second diode, again with forward basis, and then the last terminal where it goes from the + terminal to its - terminal into the ground. Hence...

So VR= Vcc - .7- .3- Vc?

VR = Vcc -.7 -.3 + Vc ?

the total for all voltages?

ok I am going to use the total voltage for the voltage drops in each diode. So for D1, the voltage drop would be Vd1 = VR - .7. Which is Vd1 = 36-.7 = 35.3 For D, the voltage drop would be Vd = VR - .3. Which is Vd = 36-.3 = 35.7 Does that help?

lol not for me. But still any ideas on the problem?

Well let's just say its not that complicated. Let's put Vc as 12 V and Vcc as 24. The diodes are forward basis where D1 is Silicon and D is Germanium. Thats all the details given. Just straightforward.

But the voltage in each point should be the same right even with a resultant voltage? What about the diodes?

Say D1 is a silicon diode( .7 volts) and D is a Germanium diode (.3 volts) Determine the voltages at A,B,C and D with respect to ground You can use hypothetical values Any help would be greatly appreciated Thanks
