No, I didn't. We have to assume that the motor is exactly in the middle of the beam and I think that would be beyond the scope of this exercise.

I used the half power method to work out zeta for the forced vibration. Then, I worked out the natural frequency with the following equations: http://www.kepfeltoltes.eu/view.php?filename=562vib.png In the case of the free vibration, the logarithmic decrement, damping ratio were found, then...

Hello Everyone, I conducted an experiment with a metal beam which had a motor attached to it in with an eccentric mass on it. The two ends of the beams were fixed with a roller and a hinge(as I remember). This was a one degree of freedom experiment. I had to collect data during free/forced...

Ohh, yes. I understand it know. Thank you! :-)

1. Ohh, I get it know. I used 1 because of the blackbody, but I know now that is irrelevant. :) 2.I added the correction factor because the thermopile should measure 0 at 0 Kelvin. Therefore, the measured irradiance is always less by 372 W/m2.

Homework Statement You are performing an experiment to validate the Stefan Boltzmann equation. What irradiance would you measure at a temperature of 109C? The emissivity of your thermal heat source is 0.81 and your thermopile measures 0 W/m2 at 27 C when directed towards a blackbody. Submit...

Part 2 is definitely no. Part 3, hmmm. That's a good question. I guess I need to ask my tutor because it could mean both as you said. Thanks. There are two more questions: I believe the answer for Q4 is part 1, definitely not part 3. I really don't know the answer for Q6.

No, definitely not. I think the answers are 1 and 4 for Q1 and Q2 also. I just would like someone to confirm if I am right:)

Any idea for Question 1.?

Yes, I noticed it. :) Sorry, I was wrong. It is a rotameter that was used to measure the flowrate.

Homework Statement Hello Everyone, We did an experiment using 3 types of heat exchangers this week, double-pipe, shell in tube and plate type. Water was flowing in the HEs, the temperature was set. We had to change the flow-rate only. After the experiment, we were given lots of online...
