But what happens when the object is on an inclined surface?

AI Thread Summary
When a 30kg block is placed on a surface inclined at 30 degrees, the pressure it exerts can be calculated by determining the normal force. The normal force (Fn) is found using the equation Fn/Fg = cos(30 degrees), resulting in a normal force of 254.6N. This value is then divided by the area of force, which is 0.008m², yielding a pressure of approximately 3.2 x 10^4 Pa (Pascals). Understanding these calculations is essential for analyzing forces on inclined surfaces. The discussion effectively clarifies the process of calculating pressure in this context.

But what happens when the object is on an inclined surface?

In this particuliar situation a 30kg block with an area of force of 80cm squared is standing on a surface which 30 degrees inclined relative to the floor. How do you calculate the pressure it exerts?

You need to find the component of the force that is normal to the surface where it acts, in order to find the pressure.
 
Ok so Fn/Fg = cos(30deg) = 0.866
0.866 * 30kg * 9.8 = 254.6N
254.6 / 0.008m^2 = 3.2 X 10^4

Like this?
 
Good work, that's it! :smile:, btw N/m^2 = Pa (Pascal).
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
Thread 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
Thread 'Correct statement about a reservoir with an outlet pipe'
The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
