AI Thread Summary
To find the angular acceleration of a solid cylinder pivoted about a frictionless axle, consider the forces acting on it: a downward force of 3N at an outer radius of 2m and a rightward force of 8N at an inner radius of 0.7m. The moment of inertia of the cylinder is given as 8 kg m^2. Understanding the concepts of torque, moment of inertia, and angular motion is essential to solve this problem. The relationship between these quantities can help derive the angular acceleration needed for the solution.

Homework Statement



A solid cylinder is pivoted about a frictionless axle as shown. A rope wrapped around the outer radius of 2 m exerts a downward force of 3N. A rope wrapped around the inner radius of 0.7 m exerts a force of 8 N to the right. The moment of inertia of the cylinder is 8 kg m^2. Find the angular acceleration.

Homework Equations



Don't even know whre to start of since i never had a problem like this in mastering physics hm. (this is from a review sheet of my physics test on Tuesday)

The Attempt at a Solution


No idea, I'm in hopes you can orientate me in this one.

You want to review the concepts of angular motion including torque, moment of inertia, angular momentum, angular velocity, angular acceleration. All of these things have their counterparts in linear motion, and the forms of the equations that relate the quantities is the same, too (which makes things easier to remember!).
 
I think i should. But i'll get back to you if i haven't been able to solve it.
 

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...
