Sound Intensity Problem of 3 Machines

AI Thread Summary
The discussion revolves around calculating the combined sound intensity level of three machines producing noise at 76 dB, 82 dB, and 85 dB. The relevant equation for sound intensity is B = 10 log (I/Io). A user initially struggles with the calculation but realizes that they can simply input the values into a calculator for the exponents. The final solution involves summing the individual intensities before converting back to decibels. The conversation highlights the importance of understanding logarithmic calculations in sound intensity problems.

Homework Statement



In a factory, 3 machines produce noise with intensity levels of 76 dB, 82 dB, and 85 dB. With all three running, what is the intensity level?

Homework Equations



B = 10 log (I/Io)

The Attempt at a Solution


B = 10 log (10e7.6 + 10e8.2 + 10e8.5)

I do not know how to evaluate this! Help please!

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged 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...
