AI Thread Summary
Arranging logs in a wheelbarrow affects the force exerted on the user's back during transport. To minimize back strain, logs should be positioned closer to the wheel, as this reduces the moment arm and the torque on the spine. A force analysis indicates that the distribution of weight impacts the force experienced by the feet, which correlates with back strain. Proper weight distribution can significantly enhance ergonomic efficiency while transporting loads. Understanding these dynamics is crucial for reducing physical strain during manual labor.

Homework Statement



Where is the best place to arrange most of the logs in a wheelbarrow so that it minimizes the amount of force on the backbone of the person transporting the load?

Homework Equations



Moment = Fd or r x F

E.O.E:
Sum of Fx = 0, Sum of Fy = 0, Sum of Fz = 0.
Sum of Mx = 0, Sum of My = 0, Sum of Mz = 0.

The Attempt at a Solution



This is basically just a force analysis problem with no weight or dimensions given. Any help would be appreciated.

Hi camino! :wink:

The force on the backbone is just the extra force on the feet.

So what will that be related to? :smile:​
 

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...
