AI Thread Summary
The discussion revolves around calculating the tension required for a box to slip on a sled on a snow-covered hill at a 22-degree incline. The sled weighs 18 kg, and the box weighs 9 kg, leading to a total weight that contributes to the forces acting on the system. Initial calculations suggest a tension of approximately 99 N based on the weight component down the slope, but this is deemed incorrect due to the absence of friction information. The need for the coefficient of friction between the box and sled is highlighted as essential for accurate calculations. Without this friction value, the box will slide if there is no friction present.

Homework Statement


A rope attached to a 18.0kg wood sled pulls the sled up a 22.0 degree snow-covered hill. A 9.00kg wood box rides on top of the sled.

Mass of Sled: 18kg
Mass of Box: 9kg
Angle of Incline: 22 Deg

If the tension in the rope steadily increases, at what value of the tension does the box slip?

Homework Equations


F=ma

The Attempt at a Solution


So I tried getting the overall tension that keeps the sled and box in equilibrium. So the tension is equal to the weight component down the slope which would be (27)(9.8)(sin 22). That gives that the tension is ~99N. So anything over that would make it slip but nope... apparently it's wrong.

Consider the friction between box and sled. (Looks like information is missing from your problem statement.)
 
The friction is not given in the problem.

If there's no friction between box and sled, the box will slide. Does your book give a coefficient of friction for wood on wood?
 
you need the coefficient of friction between box and sledge and then work with fbd of box and sled
 

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...
