Help with Statics Problem - Need Advice!

AI Thread Summary
The discussion centers on a statics problem where the user is struggling to determine the angle between the reaction at point A and the X-axis, as well as how to decompose the weight. A suggestion is made to simplify the analysis by aligning the x and y directions with the horizontal and vertical axes. The user is advised to split the forces into components and to take moments about points B and A for further analysis. This approach aims to clarify the calculations needed to solve the problem effectively. Overall, the focus is on breaking down the forces and moments to find the necessary angles and components.

Hello guyz,i'm facing this problem in my statics class...and thought posting it here so i can get some help :)

here it goes

Ok this is what i did and I'm kinda stuck...

just bare with me

I'm not able to find The angle between The reaction at point A and the X-axis so i can project... any suggestions?

and plus how shall i decompose the weight ?

Hi JosephR! :smile:

Since the only given force, the weight, is vertical, it would be simpler to make the x and y directions horizontal and vertical, and to split the normal and pulling forces into Nx Ny Bx and By.

Then take moments about B and A. :wink:
 
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'

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...
