Where are the axles on a straight truck?

A recent article, posted on MSNBC on April 22nd of this year, suggests that officials are neglecting to react to the global carbon budget as seawater acidity rises. Research is lacking needed funds, perhaps because the only solution to this problem is to stop burning fossil fuels. As the shell fish

This month's Challenge Question:

Most of our satellites have an orbit very close to the end of the atmosphere. This means they are subjected to an air drag, just like cars on Earth. In the case of cars, the drag slows down the speed. However, in the case of satellites, the drag actuall

R1=30Ω R2=20Ω R3=20Ω R4=10Ω R5=40Ω R6=10Ω I4=4A
I need to calculate U (total voltage)

I tried this:
R23=1/(1/10+1/20)=10ohm
R234=10+10=20ohm
R2345=1/(1/R234+1/R5)=1

Now that BP and the USCG have concurred that 200,000 gallons per day are leaking and that all attempts to seal the leak are fruitless.......what do the folks on CR4 have to say about a course of action.

My customer says that his LV network short circuit (SC) current is 65KA and peak SC is 137 KA. Please tell me how does it affect the motor designer. E.g is my customer expecting 65 KA to flow through the motor windings (stator/rotor) for certian duration e.g 65KA for 0.25 sec.? Please clarify.

Can you help me guys know the difference between Ith & Iu rating in MCCB?

I have an MCCB with the rating of Ue = 660 volts & Iu = 1250 Amps

It as a rating also of Ith = 800 amps max @ 45 deg C & Ir = 6300.

I have a motor for my chiller which requires a MCCB wit

What is the maximum earth fault loop for 400A MCCB. if it is taken from the manufacturer, what is the average figure?

what is the difference between moulding and casting

We are planning to replace our Chiller with bigger capacity.

The motor rating of old chiller is 375 kw whhle the new one is 570 kw, all at 380 volts, 3phase , 60 hz. The suppllier required us to a circuit breaker with minimum ampacity of 911 amps.

our existing Circuit Breaker is SA

Is Puma setting a new trend by using the science of saving resources rather than eco-hype with its new packaging? Their new shoe bag/box touts savings in resources across the board as well as reductions in carbon emissions. The packaging is made of recycled PET and is itself recyclable. Do you think

The proposed Chemical Safety Act creates some significant changes in the way that chemical companies would be required to provide safety information. While the legislation may have a positive affect on consumer safety, it could mean significant changes for the chemicals industry. What changes do you
