I would like some help with the first part of this problem. I have calculated the distributed load to be 3.82kN down as the integral of f(x) from 0 to 6 gave me that value. I found it to be 3m to the right of A as well. As such based on an analysis beam ABCD I calculated A(y) to be 3.67kN...

Please help me in understanding the history of physics regarding the atomic or non-atomic, say continous, structure of physics. In my years at school I grew up with physics of ultimate simplifications. Everything was a point "particle", like the moon revolving around the earth. Like the apple...

How are the poles of a tapered magnet distributed? Is there any way to calculate its magnetic force?

Hello, Forces can be concentrated (when acting at a single point) or distributed (when acting over a surface or line). In the case of distributed forces, we can find the resultant concentrated force by calculating a surface or line integral of the force density ##f(x)## w.r.t. an area or length...
