    Couple Moments
AI Thread Summary
The discussion focuses on calculating the magnitude of couple forces using the equation M = Fd, where M represents the moment and d is the distance between the forces. The user attempts to set up the equation with specific values but seeks confirmation on the correctness of their approach. They express uncertainty about the perpendicular distance between the lines of action of the forces. The conversation revolves around verifying the calculations and clarifying the concept of moments in relation to couple forces. Overall, the user is looking for guidance on their solution method.

Homework Statement



http://i124.photobucket.com/albums/p27/lollipopgourmet/untitled.jpg

If the couple has a magnitude of M, determine the magnitude F of the couple forces.
Since this is an X-Y plane, I assumed the equation would simple just be M=Fd, where I know the moment, and just have to add the the the forces multiplied by their respective distances.


The Attempt at a Solution



My attempt was simple set it up like this.

M=Fd
250 = F(3/5)(sqrt(17)) - F(4/5)(9)
Mostly I just want some certification that this is either right or wrong and if it's wrong to be steered in the right direction with possibly a new answer.

The moment between 2 || forces is going to be the ⊥ distance between their lines of action isn't it?

I'm not certain that's what you found.

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...
