Simple Question: Measurements of length & mass ZZZ

AI Thread Summary
Dust on samples and measuring devices can lead to inaccurate measurements, necessitating regular cleaning to ensure precision. Irregular samples can cause variations in mass and length readings, suggesting the need for standardized sample shapes or averaging multiple measurements. A slope in the balance affects weight readings, which can be corrected by using a spirit level to ensure the balance is horizontal. Other potential sources of error include temperature fluctuations and improper calibration of measuring instruments, which can be mitigated through routine checks and calibrations. Addressing these errors is crucial for obtaining reliable measurements in length and mass.

Discuss the effects of the following sources of errors on Measurements of length & mass. and suggest metods to overcome them:

1- Existing of a dust on both the sample and the measuring devices.
2- Irregularity of the samples.
3- Slope of the balance from the horizontal line.
4- Other sources.

Do you want to suggest something first? For me, 3 would be as simple as using a 'spirit-level' or horizontal surface to sort out.

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 'Calculation of Tensile Forces in Piston-Type Water-Lifting Devices at Elevated Locations'

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

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...
