AI Thread Summary
To determine the rotation direction of a circular disk with two hanging masses, the forces F1 and F2 must be calculated using the formula F = mg, where m is the mass and g is the acceleration due to gravity. The torque for each force is then found using the equation T = rFsin(phi), where r is the distance from the axis of rotation and phi is the angle. The calculated torques will indicate the net torque direction, which ultimately determines the disk's rotation. The discussion highlights confusion about the initial steps in solving the problem, emphasizing the need to calculate forces and torques accurately. Understanding these concepts is crucial for predicting the disk's rotational behavior.

Homework Statement



A circular disk has two masses acting on it, m1=10g, m2=50g. The forces caused by these masses are 4.5cm (F1) and 6.8cm (F2) away from the axis of rotation (center). The angles are 130 degrees (F1, and on outer side away from center) and 98 degrees (F2, also on outer edge away from center). Calculate F1 and F2. Which way will the disk rotate?

Homework Equations



T=rFsin(phi)

The Attempt at a Solution



I wasn't even really sure where to start with this one. Don't know if I'm missing some info or what.

Start by calculating the two forces using gravity (mg). Then find torque from these forces.
 

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 '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...
