Summarize 3 important considerations in designing circuit. Discuss the importance of pipe selection based on the important design consideration. As a mechanical engineer, design a hydraulic circuit that has linear force output. This linear force can be done with one push button and retract when push button is released. Please consider a minimal usage of components in your design. Explain the operation based on directional control valve position. Use symbols in accordance to ISO 1219. *Project Task

When we collect information for research purposes, we collect raw data. This data is great, but doesn't always end up meaning a whole lot until we draw some conclusions, organize it and look for patterns. When we organize it a bit, it then becomes what we can consider information. Information is a lot more useful than raw data. In 200 words Do any of you collect data at work? How can you best take raw data and ensure that it...

The concepts of reliability and validity are very important when it comes to the testing of intellectual abilities. When tests are given such importance (in terms of how we look at and use the numbers), they must be carefully constructed to be as accurate as possible. Could a test of intelligence be reliable, but not valid? How? Could some other measure (assessing something other than intelligence) be valid, but NOT reliable? Why or why not? Give examples. Of what practical...
