Please solve the following problems using the hardness data from the Jominy end-quench test for 8660 steel and the data for cool

ing rates at different locations in round bars during several quenches related to positions along a Jominy bar. 1. For a 8660 steel bar with a 2-inch diameter quenched by mildly agitated oil, please estimate the Rockwell hardness for both the surface and the center of the cross section of the bar. 2. A 8660 steel bar was quenched using mildly agitated molten salt. If it is required that the center of the bar should have a Rockwell hardness of at least 45, what is the maximum value for the diameter of the bar?

amm1812

Answer: The overhead percentage is 7.7%.

Explanation:

We call overhead, to all those bytes that are delivered to the physical layer, that don't carry real data.

We are told that we have 700 bytes of application data, so all the other bytes are simply overhead, i.e. , 58 bytes composed by the transport layer header, the network layer header, the 14 byte header at the data link layer and the 4 byte trailer at the data link layer.

So, in order to assess the overhead percentage, we divide the overhead bytes between the total quantity of bytes sent to the physical layer, as follows:

OH % = (58 / 758) * 100 = 7.7 %
