I've already tried it but I'm not sure I got the right answer because I don't have the answer key and I can't find it on the internet.quot;A motor having an efficiency of 88% operates a crane having an efficiency of 42%With what constant speed does the crane lift a 410-kg crate of machine parts if the power supplied to the motor is 5.5kW?quot;You don't have to tell me how to do it, I just want to see the answer you come up with.
I think the efficiency of the crane is just to confuse, unless the question stated that the crane arm was also rotating, you can ignore that figureAs it asks only for the constant speed with which the crate is lifted: I came up with 1.20 m/s, assuming that g 9.81 m/s^2
it extremely is an incorrect correlation / occasion of 'tea party revolution' by way of fact the unique tea became not shipped as suchin spite of the undeniable fact that, the packing containers might desire to be opened and then the contents deposited in the harbor as beforehand, requiring in easy terms one or 2 personsmight desire to take a at the same time as though it became a supercargo deliver packed with tea.
I can't figure out what you're trying to say
