Forced Vibration on a Cantilever Beam

AI Thread Summary
Placing a mass at the nodes of a cantilever beam under forced vibration will have minimal impact due to the lack of displacement at those points. In contrast, adding mass between the nodes can significantly influence the beam's dynamic response, potentially altering its natural frequencies and mode shapes. The discussion emphasizes the importance of understanding the beam's vibrational characteristics when modifying its mass distribution. Participants also seek recommendations for textbooks or websites that cover forced vibrations and cantilever beam dynamics. Overall, the placement of mass in relation to nodes is crucial for analyzing forced vibrations in cantilever beams.

If a cantilever beam is subject to forced vibration (from a shaker at fixed end), what will the effect be of placing a mass at a)nodes and b)between nodes?
I presume that as there is no displacement from the normal at the nodes, the mass will have little effect, but what about between the nodes?

Any textbook, or website suggestions also greatfully received!

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
