AI Thread Summary
To determine the forces acting on a 1.4 kg bottle of milk lying horizontally, the discussion emphasizes the need to analyze the forces exerted by the two surfaces it rests on, particularly considering the angle of the right surface at 45 degrees. Participants suggest using fundamental equations such as F=ma and w=mg, while also considering the resultant force through trigonometric functions like cosine and sine. The importance of identifying all acting forces and calculating the net force, especially the vertical components, is highlighted. Confusion arises from varying attempts at solutions, indicating a need for clarity in the calculations. Accurate resolution of this problem requires a systematic approach to force analysis.

which calculation should i use??@_@

Homework Statement


a 1.4 kg bottle of milk is lying horizontally in the rack. the two surfaces on which the bottle rest r 900 apart, and the right surface makes an angle of 450 with the respect to the ground. each surface exerts a force on the bottle that is perpedicular to the surface. determine the magnitude of each of these forces
* the bottle is lying 90 degree vertically


Homework Equations



f=ma?
w=mg?
or should i find the resultant force by using cos and sine


The Attempt at a Solution


ive tried..but all the answer are different..

Call the force exerted by each surface on the bottle F. What other forces act on the bottle? What's the net force on the bottle? Consider vertical components.
 

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...
