Homework Statement If a question gives us a max load with different extensions, how do I calculate the strain? For example: 1900KN=x mm 1900KN=x mm 2000KN=x mm 2000KN=x mm 2000KN=x mm 1900KN=x mm 1900KN=x mm Homework Equations strain= ΔL / L The Attempt at a Solution What I think is...

My textbook just says to refer to appendix for K values. It doesn't say anything between the transition of 2 different pipes with different diameters.

So the answer between the transition of two pipes is (0.03/0/05)^4 ?

Homework Statement Homework Equations N/A The Attempt at a Solution Usually we are given a table, but how do we calculate the loss coefficient between 2 different pipes with different diameters? In this case, between the 5 and the 3 cm^2 pipes?

Homework Statement Hi everyone, I need help finding the centre of gravity for this object in order to find its stability in water. However, I am having trouble finding out the centre of gravity. Homework Equations N/A The Attempt at a Solution [/B] The answer says that it is 1, but...

What is the difference between Q=m(u2-u1) + W & Q=m(h2-h1)? Basically I am trying to figure out 2 different sets of questions and apparently using these separate equations yield different answers, and I don't know which equation to use. From my understanding, both of them are used in...

Thank you for clearing up the confusion!

Homework Statement The maximum proposed stress of their new design is 670MPa. You have measured the tensile strength of pieces of their steel, using an appropriate "standard" to guide you. (What does this even mean?) The load vs displacement graph is given. The steel sheet is 3mm thick. The...
