Engineering - September 2007

For my lab, we built a ripple counter by hooking the output to the clock of the next JK Filp Flop. Since the rest are unconnected, they all are a vaule of high (or 1 or True or on etc.)

Starting at 0 0 0 0 ( a four bit counter)

When the clock0 goes to 0 to 1, we get 1 for the Q0 on the first bit. Since, Q0 goes from 0 to 1, the Q1 remains the same meaning zero.

Now here's my problem... what is the logic for the remaining bits? My assumpition is since Q1 (or clock2) remains the same, the previous state remains.

So, the main part of the logic is just based the first few bits.

I am trying to use a FET with a BS2 to be used as a "people sensor". Is this possible? Would the schematic at this link (http://www.amasci.com/electrom/electro-f1.gif) work?

Consider the sections of two circuits illustrated above. Select True or False for all statements. Rab (parallel circuits) Rcd( series)
1. After connecting c and d to a battery, the current through R3 always equals the current through R4.
2. Rcd is always less than or equal to R3.
3. Rab is always less than or equal to R1.
4. After connecting a and b to a battery, the voltage across R1 always equals the voltage across R2.

A question for software engineers. Can you draft an SRS for an existing commercial product within 24 hours? That is, can one be created that would withstand scrutiny against ISO 13485?

Serious answers only please.

A piece of plywood in which several holes are being drilled successively has been secured to a workbench by means of two nails. Knowing that the drill exerts a 12 N-m couple on the piece of plywood, determine the magnitude of the resulting forces applied to the nails if they are located
(a) at A and B
(b) at B and C
(c) at A and C

Ok, i need a little help with this. It's involving electricity, obvioiusly. So, an object has a resistance of 15 ohms, a voltage of 45 volts, an electric current of 3, the power of it is 135. After giving you these facts, I'd appreciate it if you could answer the question. The question is

What is the cost of operating this object for 10 hours at a rate of $0.08 per kWh?

I didn't understand the question, so maybe someone that understands electricity better than me can help solve this question. If you have taken the time to even read my question, thank you. Any help is highly appreciated.
