Shear Stress Due to Angular Deceleration

AI Thread Summary
The discussion focuses on calculating shear stress in a rectangular block (propeller) undergoing angular deceleration. The block has defined dimensions and uniform density and is initially spinning at a constant angular velocity. The goal is to establish the relationship between radial distance from the centroid and shear stress during deceleration. Understanding this relationship will help determine the maximum shear stress experienced by the block. Assistance is sought to derive the necessary equations for this analysis.

I have a rectangular block (propellar) with known width, thickness, legth, and uniform density. It is spinning at a constant angular velocity around its centroid. Then it is decelerated at a constant rate to rest. I want to find the relation between the radial distance from the centroid and the shear stress during the decelleration, so that I can determine the maximum shear stress. Please help! Thanks!

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
