Why should dc series motor can be operated for no load and light load?
dc motors can be operated at no load as well as at load condition.But by using the swin burns test the efficiency can be calculated at no load which is more benficial than load test.At industries this swin burns test is used because for load test we have to give separate supply for the load to run.In no load test that power is saved.
How do you calculate the power for an overhead crane to size the cable and breaker disconnect switch?
If you really have an overhead crane to install it would also be likely that you would either know how to do the installation already or would know that such work should only be done by a licensed electrician... <><><> It would be easier to give you a more helpful answer than this one if you had described the crane and the size of its motors. You need to give such basic details as the output horsepower of the electric motors used to turn the crane and lift the load, their operating voltages and current consumptions... <><><> This seems like a question from an electrical course, and is probably best answered by referring to your course materials. It's your test question, not ours, and there won't always be someone else to ask for the answer. Earn your diploma.
What is the of significance initial load in Rockwell hardness test?
the answer is 10KGF
What is the difference between static load test and dynamic load test?
The difference between static load testing and dynamic load testing is that with static load testing a certain percentage of a product is tested against a group of specifications. During dynamic testing each individual product is tested against a group of standards based on previous tests.
What is tension test?
A tension test in which a specimen is broken by applying in increasing load ot the two ends.During the test the elastic properties and ultimate tensile strength of the material are determined.After rupture the broken specimen may be measured for elongation and reduction area.
What is tipping load?
The tipping load is the hook load at a specified radius about a line called the tipping fulcrum, which causes the crane to tip. The crane rating is based on taking a percentage of the tipping load. In the United States and Canada, the ASME crane load rating is 75 percent for crawlers and 85 percent for truck cranes of the tipping load. In other industrial countries the crane load rating is 66.67 percent and 75 percent, respectively. A crane will tip when the overturning moment (moment of the load and boom about the tipping fulcrum) becomes close to equal to the crane resisting moment (moment of the machine weight about the tipping fulcrum). A stability test is conducted for truck and hydraulic cranes when the machine is in a state of balance about its tipping fulcrum. At this condition, the entire weight of the machine and load is being supported on two outriggers
Is it required have a test certificate of concrete bucket which is lifted by crane?
Yes it is required by most registered companies. The HSE Law states that a proper load test certificate is issued with the bucket , aswell as weekly maintanance checks. Some companies that sell the concrete buckets issue the load test certificate with the equipment.
What is the initial load in Rockwell hardness test?
The initial load in Rockwell hardness test is 10KGf.
How do you load test a Harley Davidson motorcycle battery?
You can take it to a battery place and they can test it under a load.

In weight test what is the difference between a static test load and a dynamic test load?
A static test load is applied gradually and held constant to measure the structure's deformation and ultimate load-carrying capacity. On the other hand, a dynamic test load is applied rapidly and repeatedly to simulate real-life conditions and assess the structure's response to dynamic loads such as wind or seismic activity.
How would you calculate a dead weight load on a structure if you test it with a hydraulic press and the press gauge reads 1000 psi and the contact area on the structure is 2 sq in?
The dead weight load can be calculated by multiplying the pressure (1000 psi) by the contact area (2 sq in). In this case, the load would be 2000 pounds.
What is load test on single phase transformer?
A load test on a transformer is done to make sure it stays within its designed temperature range while on full load.
What test is most accurate for batterys?
Battery load test

What is the average salary of a crane driver IN UK?
£100, 000, 000 per minute! NOT KIDDING, I USED TO BE A CRANE DRIVER AND AS PART OF MY CRANE DRIVING TEST WE HAD TO FIND OUT AVERAGE STUFF ABOUT THE JOB :)
Load test on 3 phase induction motor?
When you do a load test on a 3-phase induction motor you are checking the power factor, viz slip, and efficiency of the motor. You can test various loads with this test.
