How Do Friction and Incline Angle Affect Forces Between Two Sliding Masses?

AI Thread Summary
The discussion focuses on calculating the forces between two sliding masses on a rough incline at a 48-degree angle. Weight 1 (3.5 kg, coefficient of friction 0.55) and Weight 2 (7.0 kg, coefficient of friction 0.10) are initially at rest and begin to slide, with Weight 2 pushing Weight 1. Participants emphasize the importance of identifying the forces acting on each mass and drawing free-body diagrams to approach the problem effectively. The conversation seeks guidance on how to start the calculations and apply relevant equations. Understanding the impact of friction and incline angle is crucial for solving the problem accurately.

Homework Statement


Two weights are placed on a rough incline, inclined for 48 degrees. Weight 1, m1 =3.5 kg has coefficient of friction of 0.55 and weight 2, mass m2=7.0 kg, has coefficient of friction 0.10. Initially, weights 1 and 2 are placed one after the other and are at rest. They start sliding downt the incline, weight 2 pushing weight 1. Calculate the force bewteen the weights 1 and 2.

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...
