As usual beautiful explanation... Sir.. One small query please. in these questions, coordinates are pre draw, if we are in some practical scenario and we have to then choose coordinate, how do we draw them ? if there are certain points we need to consider as to where to choose origin and x,y,z direction ? if Hibbeler book mentions about it in some chapter in detail ? Thank you

You can draw your own axes, but in order for the cross product to work correctly the axes need to obey the “right hand rule” for axes. If there are no axes drawn I usually define them exactly like in this problem.

[@engineeringdeciphered]

and no, it does not matter where you put the origin
