Consider sending a 2500-byte datagram into a link that has an MTU of 500 bytes. Suppose the original datagram is stamped with the identification number 727. Assume that IPV4 is used. The IPV4 header is 20 bytes long. How many fragments are generated? Show calculation.
What are the values of the fragmentation-related fields in the generated IP datagram(s)? Show all work. Hint: The following 4 items are expected: size, value of its identification, fragment offset, and fragment.

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

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.

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
