Per Power Work

AI Thread Summary

To calculate the power of a machine performing 1800 N-m of work per minute, it's important to recognize that N-m is equivalent to Joules, a unit of energy. Power is defined as work done over time, so the formula for power is work divided by time. Given that the work is 1800 Joules and the time is one minute (or 60 seconds), the power can be calculated as 1800 Joules divided by 60 seconds. This results in a power output of 30 Watts. Understanding the distinction between Joules and torque is crucial for accurate calculations.

N-m is better known as Joules (energy, work) and not to be confused with Torque which has the same dimensions. Work/time is power.

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:
