6.26 The velocity components in an ideal, two-dimensional velocity field are given by the equations 3(x² − y²) - U = V = - 6xy All body forces are negligible. (a) Does this velocity field sat- isfy the continuity equation? (b) Determine the equation for the pressure gradient in the y direction at any point in the field.

a. What is the ideal mechanical advantage of this system? The inclined plane dimensions are 7.2 meters length and 1.8 meters height.b. What effort force is required to move the 600N create? c. In practice, you need to supply an effort force of 75 N to lift the crate. What is the efficiency?d.  How could you redesign this compound machine so that the effort force needed was 50 N in practice? Assume the efficiency is your response from part C no matter what changes you make. Be specific with the changes you propose (if you add pulleys state how many, if you change the inclined plane dimensions state the new dimensions, etc.).

Hello, I was just wondering how you find hte angle of the blocks to 45 degrees? Thank you!

kindly answer it
