What Does an 8% Grade Mean in Terms of Slope Steepness?

AI Thread Summary
An 8% grade indicates a slope where for every 100 units of horizontal distance, there is an 8-unit vertical drop. This means the slope is equivalent to a rise of 8 units for every 100 units traveled horizontally. In practical terms, it represents a relatively steep incline or decline, affecting vehicle control and stopping distance. Understanding this concept is crucial for drivers to gauge the potential risks associated with steep grades. The discussion highlights the need for clarity on how grade percentages translate into real-world driving scenarios.

I have no idea what a 8% grade is. I am guessing it is a slope, but how much?

Thanks for any help I am stumped.

Yes it is a slope of 8/100
 

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...
