    Where can I study this type of problem? (fluid dynamics)

    Hello everyone! I have to study for an exam, of which I have just retaken the subject (fluid dynamics) and I don't feel very good. In my language (Spanish) I find these similar problems, but in English I only find problems that do not include these types of arrangements. I know that the...

    Help with this mechanism (acceleration with graphic method)

    Hi guys! I have problems with this mechanism...finding the aceleration with graphic method. I already have drawn the speed diagram and the values of all of them. But, i dont know if my aceleration diagram it is well drawn. I'm stuck especially when trying to plot and calculate the...

    Engineering An issue with these two curved beam homework problems

    I am very sorry, they have already been corrected in the main text. In the first problem it does not have a load, so the "P/A" is omitted from the formula. In the second it is 5KN the load

    Engineering An issue with these two curved beam homework problems

    Hi, good evening/morning/night! I have a problem with this 2 homework problems about curved beams. In both I must calculate the stress at points A and B. My procedure is correct, but for some reason in: First problem - the effort in A is very close to that of the teacher, but the effort in B...

    How to Implement 25us Delays in PIC16F84A PWM Code?

    Hello how are you :D I have some problems with my code, which is to control the speed of a DC motor by pwm with the pic16f84A. I already have the combinations and the diagram of the signals, but I still need to implement the part in bold. How would the delays be implemented so that they have...

    Engineering Help with my Karnaugh map circuit: it does not work

    Hi! Good night ;) I have made the simplification of my circuit from the truth table using maps of. Everything looks good, however the simulation does not work in many cases according to the truth table. I notice that my boolean equation taken from the maps looks very big, is there the error...

    Is it enough to format a computer/phone for erase a malware/virus?

    I have a question about a infecting computer or smartphone: If was infected and the contents can be viewed in real time in other equipment... its enough to format for clean the computer/smartphone? or the "ip" needs to be change or is required use a VPN? How its infected this kind of...

    Engineering (A+B)(A+C)=A+BC circuit doest not work (protoboard)

    The schematic corresponds to A+BC. I use logic probe like switches in the schematic, Vcc and ground are the blue connections in the first image.
