Suppose we want to transmit the message 11101011 and protect it from errors using the crc polynomial x3 +1. a) use polynomial long division to determine the message that should be transmitted. b) suppose the leftmost bit (most significant bit) of the message is inverted due to noise on the transmission link. what is the result of the receiver’s crc calculation? how does the receiver know that an error has occurred?

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

Condition monitoring is a major component of. (clo4) a)- predictive maintenance. b)-preventive maintenance c)-proactive maintenance d)-reactive maintenance.
