Question

The larger the number of bits of an analog to digital converter, the higher the resolution error. Select one: O True O False .00 A scaled-down prototype of an axially loaded beam is desired in order to perform tests to determine its structura properties. Assuming the beam operates within the elastic region, Hooke's law can be used to determine the amount of strain in the beam using the equation below. (F/A) € = E cion The beam has a square cross-sectional area in which the length of each side for the prototype is scaled down by 8. The prototype also uses the same material as the model. Given the above information, how much force must be applied on the prototype? Select one a 1/4th b. 8 times CC 1/8th 0.64 times e 1764th

Answer 1

0.00299VD Co-2.99 mv y Ano) Resolution Erroom At is an error of an A 12-bit ADC with a maximum input 7 JOVDC con resolve the measurement into lovio analog computing unit that results foom ints inability to respond to changes of less than a given magnitude. Analog-fo- Digital Converters (ADCs) transform an analog Voltage to a binary number and then eventunery to a digit number for reading on a meter, monitor or chort. - the number of binary digits thíos de poezent the eligit of numbes determing the ADC Resolution Anno bit ADC has a resolution of one Đ post in an *** The larger the number of bits of on analog to digital converter, the higher the resolution error. False Explaination : + A12-bit ADC hos o ver sfutin of one post in 4096.lie. ?"= 212= 4096) - this loVoc gogo error in this case is and the quantization CS Scanned with CamScanner

0.0122 12.7 specified to be no more than half of the least significant hit. For the 12-bit ADC, the erros is $1.22m v Andir for 16-bit ADC has a resolution of one post in 216.10 Thus, o 16-bit APC with a maximum input of lorde con resolve the measurement in'to lOVDC/216 = 0.459 mv and the quantization estos in this case is specified to be no a more than half of the least significant bit. For the is 0.153 16-bit ADS, the error = 0.0765 mv (0.007657). Q2j anej Given Relation mv 2 F E = AE op = E= stran = change in length original length FE Force Applied A = Cool-section E = Young's Modules, It is fundamentes property of every material that cannot be 2. changed (side) 27 E + AE - R sp. p? 1936 2 FE Now, l FC) CS Scanned with CamScanner

IF = Blade Here, the material is some, so E(Yerung's Modules does not change so, TE & fie. Ipoototype = morep Hence, force opplied on the prototypes ㅎ times of Force applied on Model Hence, option stion [c 8 7 is correct CS Scanned with CamScanner
