Can Hurricane Pressure Cause Roof Damage Like It Does to My Skin?

AI Thread Summary
Hurricane pressure can create significant differences in pressure on roofs, similar to how it affects skin. The high wind velocity over a roof leads to low pressure above and high pressure below, potentially causing roof damage. However, the human body, being mostly incompressible water, would not experience explosive decompression in the same way. Concerns about lung issues arise in extreme pressure changes, such as in space without a suit. Overall, while roof damage from hurricanes is a real concern, human skin does not react in the same explosive manner.

Would the pressure on my skin, try to explode out, just like a hurricane and a roof, in which the high velocity over the roof causes low pressure ontop of the roof and high pressure beneath the roof?

You might have an issue with your lungs depending on how you came to be in space without a space suit, but that aside, since your body is mostly incompressible water, it would not explode.

Thank you good sir!
 
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...
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...
