we have ' large brass pin to be fitted in a steel block' so we should cool the pin (so that it should contract) and heat the block (so that it should expand)...
Not "Heat the pin (it becomes more large by expansion) and cool the block (it becomes more short)"...This will create more problem to you instead.

3. Calculate the maximum temperature of a brass pin with 20 mm x 20 mm cross section sliding on a AISI 1095 steel disk at a relative velocity of 1 mm/s and a high stress of 2 GPa in the dry condition (u = 0.22). Assume that the entire surface of the brass pin contacts the steel surface. Mechanical and thermal properties of the two materials are given below: Material Bulk hardness (GPa) Thermal diffusivity (mm/s) Thermal conductivity (W/m K)...
2) The rigid bar CDE is attached to a pin support at E and rests on the 30-mm diameter brass cylinder BD. A 22-mm-diameter steel rod AC passes through a hole in the bar and is secured by a nut which is snugly fitted when the temperature of the entire assembly is 20°C. The temperature of the brass cylinder is then raised to 50°C while the steel rod remains at 20°C. Assuming that no stresses were present before the temperature...

2. A nominal hole size of .6250 inch diameter and a RC6 class fit has been selected. Calculate the hole and shaft sizes and their tolerances. 3. A nominal hole size of 12 mm diameter and a H7/k6 class fit has been selected. Calculate the hole and shaft sizes and their tolerances
7. Find the maximum and minimum diameters for a hole-and-shaft pair with an LC-2 fit. The nominal diameter is 1-3/4".

Suppose that a huge file is stored in secondary storage. It is much too large to fit into main memory. Describe an algorithm for sorting the file. You should try to minimize the number of page reads and writes. You can create extra files, of any size, on secondary storage if you need them. Say what you can about both the run time and the number of page accesses used by your algorithm. To make things definite, you might consider...
The following questions are from a copper content in brass experiment in my Chem 1 lab class. These are the discussion questions, I would like a little bit of background knowledge on how I may get the answers so I could fully understand. Thank you! The equation for your line has a nonzero y intercept. Beer’s law does not have an analogous term. Explain the discrepancy between your experimental best fit equation and the theoretical Beer’s law equation. 2. Consider...
