Resolve Forces Homework: Magnitude & Direction

AI Thread Summary
The discussion focuses on resolving forces to determine the magnitude and direction of resultant forces. A user is struggling with their answers on masteringengineering.com, indicating their calculations may be incorrect. Another participant points out a potential error in the user's calculation for Fnet, x, suggesting a review of the negative sign in the F3y component. After addressing this issue, the user successfully arrives at the correct answer. The conversation highlights the importance of careful attention to signs in vector calculations.

Your setup for Fnet, x looks right, but I get a different numerical result for Fnet, x.

For F3y you have -33 sin (330). Should you include the negative sign in front of 33?
 
Good point with the negative sign! I got the answer now. Muchas gracias muchachos!
 

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'

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...
