Visualizing Liquid Pressure: A Diagrammatic Guide

AI Thread Summary
Liquid pressure exerts a net force that is perpendicular to surfaces in contact with the liquid. A user seeks clarification on a diagram from their textbook, which depicts a triangle submerged in water with three perpendicular force vectors. There is confusion regarding the absence of non-perpendicular vectors and how they cancel each other out. The discussion emphasizes the importance of visualizing these forces to understand the concept of liquid pressure better. A clear diagrammatic representation could enhance comprehension of these principles.

The forces of a liquid pressing against a surface add up to a net force that is perpendicular to the surface.

I cannot visualize this. Could someone help me out diagrammatically here?

The diagram given in my book is a triangle placed in water and three perpendicular force vectors are shown but i don't why the other non-perpendicular vectors haven't been shown. The book mentions that the non-perpendicular components cancel each other but
again i cannot picture them canceling each other, duh!
 

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'

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...
