Calculating Otto Engine Clearance w/ Efficiency 46.4% & k=1.3

AI Thread Summary
To calculate the clearance of an ideal Otto engine with an efficiency of 46.4% and k=1.3, one must understand the relationship between efficiency, work done, and heat added. The efficiency formula is defined as efficiency = Worknet/Heat Added. With k set at 1.3 and a hot air temperature of 1900K, applying the principles of the Otto cycle is essential for deriving the clearance. A resource link was provided to assist with understanding the Otto cycle's air standard efficiency derivation. Understanding these concepts is crucial for solving the problem effectively.

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...
