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).

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
