    Drawing Weight
AI Thread Summary
The discussion revolves around calculating the torque created by a 49 N weight attached to the foot of a lower leg, with the leg extended at an angle θ from the vertical. A participant questions whether the angle should be considered as the force's angle with respect to the distance (r) and contemplates if the angle should be adjusted to 90 - θ for accurate calculations. Clarification on labeling in the diagram is requested to better understand the concept of torque. Ultimately, the participant indicates they have resolved their confusion but seeks further confirmation on the labeling. The conversation highlights the importance of understanding torque in relation to angles and lever arms in physics.

Homework Statement



The drawing shows a lower leg being exercised. It has a 49 N weight
attached to the foot and is extended at an angle θ with respect to the
vertical. Consider a rotational axis at the knee.
a. When o
θ = 90.0 , find the magnitude of the torque that the
weight creates

Homework Equations





The Attempt at a Solution



Shouldn't the angle be the force (weight) with respect to r? Here is r with respect to r perpendicular, or did I get the labels wrong? If it is the case, should we solve the angle by 90 - theta?

I get the answer but I don't get the concept. Can someone help me with the labelling?
Great appreciated if you can explain it on the diagram, thanks!

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'

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...
