Angular Angular velocity Hinges Spring Velocity

AI Thread Summary

The ideal angular velocity for a door with spring hinges to close automatically is typically around 30 to 60 degrees per second, ensuring a smooth and controlled motion. Existing designs often incorporate this velocity range to balance efficiency and safety. Factors such as hinge tension and door weight also influence the closing speed and should be considered in the design. Many manufacturers have established standards based on these parameters, making it feasible to copy existing designs for optimal performance. Overall, achieving the right angular velocity is crucial for the effective functioning of spring-hinged doors.

Can someone tell me what is the best angular velocity to be exerted on the door for it to close automatically if I were to design a door with spring hinges.

This is probably done already. Copy existing designs?

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
