On a frictionless table, a glob of clay of mass 0.40 kg strikes a bar of mass 1.74 kg perpendicularly at a point 0.15 m from the center of the bar and sticks to it. If the bar is 1.14 m long and the clay is moving at 6.6 m/s before striking the bar, what is the final speed of the center of mass...
I'm looking for the hardness value for Steel 4130, Steel 1018, Al 6061-T6, and Brass 360. (Rockwell-B).
Is there a website where I can find these value?
Thank you!
Hello there, I am wondering if you could offer some help on this questoin, I have been attempting to work through it, however cannot see exactly what route I should be taking to try and solve it;

Ok, using steam tables, calculate the specific entropy of steam with dryness fraction 0.63 and pressure of 2MPa.
Can someone suggest how Id go about this?
Thanks.
Are there any good tables showing the convergence of common summations? I am convolving some discrete time signals and they can get very tricky. Thanks all
Hello everyone, I don't want to implement the rest of this circuit if i messed the truth table up! So i was wondering if someone can take a look to see if the truth table seems to hit all the cases and looks correct.

Hi guys.
I have to do a little written report about Periodic table and I have to write either about Groups, Periods or Transition elements.
I have decided to write about Periods. First I wrote what a periodic table is and how it is formed (just a little histry) then I explained the order...
I have two measurements for the length of a table (the table is not perfect so it is prudent to measure it on both sides). I get a +/- b and c +/- d as the measurements. Suppose b does not equal d. How can I find the average and uncertainty of the length of the table?
the lab involves an air hockey tab set up on a slight angle (one side is raised by a textbook) and the puck is pushed in such a way as to create what looks like a parabolic shape on the paper with carbon markings. The point is to determine if the motion is a projectile motion. So far, my group...
I was doing a simple experiment with my class to demonstrate the boiling point of water.Two of the students wanted to see what would happen when we added salt. So, the students added about 50 ml of common table salt to less than 200 ml of boiling water. The temperature of the water immediately...
