Finding angular acceleration as a function of time.

AI Thread Summary
To find the angular acceleration as a function of time for a fan blade with angular velocity omega_z(t) = gamma - Beta(t)^2, differentiation of the angular velocity function is necessary. The discussion highlights confusion among participants regarding the differentiation process, with one user suggesting that acceleration can be derived from velocity through differentiation. Another participant expresses frustration over previous comments while admitting to errors in their calculations due to integrating instead of differentiating. The conversation emphasizes the importance of correctly applying calculus principles to solve the problem. Ultimately, the key takeaway is the need to differentiate the given angular velocity function to determine angular acceleration.

A fan blade rotates with angular velocity given by omega_z(t) = gamma - Beta(t)^2 .


Calculate the angular acceleration as a function of time.


I don't even know where to begin and my book is all but useless. Any ideas?

Are you serious?

Here's one idea: differentiate!
 
Well, if this was velocity and accelaration you could think of velocity as dv/dt and acceleration by d²v/dt², from this we could clearly go from one to the other...
 
Hey I'm sorry I'm not a physics genius like you are cepheid. I appreciate the help but I can do without the snide comments. Anyway, I was leaning toward differentiating and I tried it and came out with a wrong answer. Computations were probably inaccurate though.

Thanks, my calculus is a bit rusty and I integrated instead of differentiated...
 

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 'Minimum mass of a block'

Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...

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...
