Is Energy Density Homogeneous with Stress and Strain Units?

AI Thread Summary
Energy density is defined as the energy stored per unit volume, and the expression for energy density is given as 1/2 Stress multiplied by Strain. The discussion focuses on whether this expression is homogeneous with respect to units. Participants emphasize the importance of providing an attempted solution or thoughts when seeking assistance. Clarifications on the relationship between stress, strain, and energy density are sought to ensure understanding of the topic. The conversation highlights the need for adherence to forum guidelines while exploring fundamental physics concepts.

hey guys this is my first post to the forum so excuse me if I am posting at the wrong topic :D

My question is the following:

" Energy density is the energy stored per unit volume. Show that the expression of energy density is 1/2 Strees X Strain in homogenous with respect to units "

Thank you

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...
