How can I calculate the moment of inertia for a rod bent into a square shape?

AI Thread Summary
To calculate the moment of inertia for a uniform density rod bent into a square shape, first confirm that the side length "a" is equal to L/4. The axis of rotation is typically considered at the center of the square. The moment of inertia for such shapes can be derived using integration or by applying the parallel axis theorem. It is essential to account for the distribution of mass along the bent rod when performing these calculations. Understanding these principles will aid in accurately determining the moment of inertia for the square configuration.

So i have a uniform density rod of mass M and length L. Now i want to bend it into a square shape with side length "a" where a is equal to "4/L". The thing is i only know how to calculate moment of inertia for objects with constant radii. does anybody have any recommendations to help me along?

I think you mean a is equal to L/4. Where is the axis of rotation? The center of the square?
 
yes... in both cases lol
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
