How to Calculate Net Torque on a Beam about Different Axes

AI Thread Summary
To calculate the net torque on a beam about different axes, it is essential to know the beam's length and the points of application for the forces. The beam in question is 4 meters long, with a reference point at 2 meters. Users are advised to upload images to a hosting site or attach them directly to the forum for clarity, as local files cannot be accessed. The discussion emphasizes the need for clear visuals to assist in calculating torque about Point O and Point C. Proper torque calculations require understanding both magnitude and direction, typically expressed in Newton-meters.

Don't know if the image worked. I think if you copy and paste it into browser it might work.

Calculate the net torque (mag and direction) on the beam in the figure below about the following axes. Beam has length 4m, so r=2m

a) an axis through Point O, perpendicular to the page.

________ N*m counterclockwise

b) Through Point C, perpendicular to page

________ N*m counterclockwise

No, since it references a file on your PC, which we don't have access to. You have to upload the image as an attachment or put it on some image hosting site.
 
well i can't c anything recommend you some site such as flickr, photobucket, and others
all are nice well renowned photo hosting site or you also can upload to the forum as attachment
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

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 hanging mass'

Thread 'A cylinder connected to a hanging 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...
