AI Thread Summary
To determine the tension in the cable supporting a 20-kilogram beam with two suspended masses (M1 = 40 kg and M2 = 20 kg), it is essential to sum the forces and torques acting on the system. Breaking the forces into X and Y components will aid in setting up the equations needed for analysis. The relevant torque equation should include only the forces that create torque about the pivot point. A similar example from the textbook, involving a man standing on a beam, can provide a useful model for solving this problem. Understanding the forces and their contributions to torque is key to finding the tension in the cable.

Homework Statement


A uniform 20-kilogram beam is supported in a horizontal position by a pin and cable as shown in the figure. Masses M1 and M2 are suspended from the beam. If M1 = 40 kg and M2 = 20 kg, what is the tension in the cable?

I am sorry. I can not see a figure so I have no idea what the situation is like :(
 
james, sum the forces and sum the torques.

Break the forces into X and y components before you set up your equations

Then figure out which forces actually have torque and set up a ∑tau equation for that. At that point just solve for T. There is an example in your textbook of a problem similar to this one, use that as a model.
 
Which example are you talking about?

the one with the man standing on the beam. the only difference is that now you have the forces from the two masses as opposed to just one from the man.
 

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...
