    Choosing dye to color glycerine for flow visualization demo

    Hi, I am planning to do this as a demo in my fluid mechanics class. I've used glycerine as corn syrup isn't available. It seems to be transparent and viscous enough. Can anyone please suggest a dye? The video seems to be using coloured corn syrup for flow visualization. How can I...

    Minimizing the maximum bending moment

    That was a vague hint. I got the problem in the mean time though. It was fairly straightforward.a=\frac{1}{(1+\frac{1}{\sqrt{2}})}L

    Minimizing the maximum bending moment

    Homework Statement Refer to the attachment provided Homework Equations Just taking force and moment equilibium of whatever component I choose. The Attempt at a Solution I assumed a uniform force distribution. Set the origin at the leftmost end. For 0< x < \frac{L-a}{2} The...

    Which C-H bond has lowest bond energy in allylic carbanions?

    Homework Statement Look at the diagram accompanying the question. Which has least C-H bond energy? The Attempt at a Solution On cleavage of a C-H bond, a carbanion is formed as carbon is more electronegative than hydrogen. So cleavage of (b) results in a carbanion stabilized by resonance
