Get Help Determining Internal Forces for Part A

AI Thread Summary
The discussion focuses on determining internal forces necessary for calculating stresses in a specific homework problem. A user seeks assistance with understanding the relationship between forces depicted in their diagram. Another participant suggests using an overall force balance to relate F1 to Pc, which is crucial for solving the problem. By substituting this relationship into existing equations, the user can derive the remaining forces needed. The conversation emphasizes the importance of establishing connections between forces to solve the problem effectively.

You almost have it. From an overall force balance, how is F1 related to Pc? Once you establish this, substitute it into the equations you have already developed. This will give you all the rest of the forces.

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...
