AI Thread Summary
To determine the tolerable temperature variation for a Hall effect magnetic sensor operating at 40°C with a ±5% accuracy requirement, one must analyze the Hall voltage graph against absolute temperature. By identifying the Hall voltage value at 40°C, the corresponding error range can be established. This error range will indicate the temperature limits within which the sensor maintains the required accuracy. The discussion highlights the importance of understanding the relationship between Hall voltage and temperature to calculate the acceptable variation. Ultimately, this approach clarifies how to ensure the sensor's performance remains within specified accuracy limits.

Then you know what an error range of ±5% from that looks like. What temperature range does that correspond to?

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...
