Calculating Center of Mass of a Hollow Nose Cone

AI Thread Summary
To calculate the center of mass of a hollow nose cone, the formula is given as π&radic(h2+R2)hR/M, where R is the base radius, h is the height, and M is the mass. An alternative method involves suspending the cone from different points and marking the vertical lines created; the intersection of these lines indicates the center of mass. This approach can help in practical applications, such as determining fin placement for a rocket project. The discussion emphasizes the importance of accurately finding the center of mass for stability in rocket design. Understanding these methods is crucial for successful rocket construction.

I am working on a rocket and need to find the center of mass of a hollow nose cone. Any help would be appreciated.

If the "nose cone" is a cone with base radius R and height h, with mass M, then the center of mass is on the axis at distance π&radic(h2+R2)hR/M.
 
Here's an alternate way, if its any easier for you. Suspend the hollow nose cone from a chosen point (by attaching a string to any point of the cone) and there will be a vertical line (90 degress relative to the Earth). Remember where this vertical line is. Then choose a different suspension point. The center of mass is where these two vertical lines intercect. Look at the pic if it helps. And make sure to do this with the same "side" of the cone.

Are you doing a math problem, or a lab?
 
thanks for the help. I am working on a big rocket project and needed to find the center of mass for each part so we can figure out where we need to locate the fins.
 
Thread 'Collision of a bullet on a rod-string system: query'

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...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
