AI Thread Summary
Torque is a crucial concept in understanding how a wheelbarrow enables the transportation of heavy loads with less lifting force than the load's weight. The wheelbarrow's design allows the user to apply force at a greater distance from the wheel's axis, effectively increasing torque and reducing the effort needed to lift the load. In the case of a 10-speed bicycle, when in first gear, the chain is on the gear with the smaller radius, which provides higher torque for easier pedaling. When Dana and Loren carry a steel girder, Dana, holding it at the end, exerts greater torque due to the longer distance from the pivot point, resulting in a greater force requirement on her part. Overall, torque plays a vital role in mechanical advantage across these scenarios.

apply the concept of torque to explain how a wheelbarrow allows you to transport a heavy load with a lifting force than the weight of the load

a 10-speed bicycle has five gears on the rear wheel. when the bicycle is in first gear, is the chain on the gear with the largest radius or the smaller radius? use the concept of torque to explain your answer

dana and loren are carrying a steel girder. Dana is holding the girder at the end while loren is not. who is exerting the greater force on the girder? justify your answer using the concept of torque

So ... what are your thoughts on how torque plays a part?
 
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...
