Calculating Shear Stress in a Steel Drum

AI Thread Summary
To calculate the shear stress in the steel drum, the volume of oil must first be determined, which is based on the drum's dimensions and the oil's density. The shear stress can be calculated using the formula τ = F/A, where F is the force due to the weight of the oil and A is the area of the drum's cross-section. The factor of safety can be assessed by comparing the calculated shear stress to the ultimate strength of the material. The thickness of the plate and its Young's modulus are also relevant for determining the drum's structural integrity. Further guidance is needed to proceed from the volume calculation to the shear stress calculation.

Homework Statement


A steel drum contains oil with a density of 0.712 and is standing on one of its ends. It has a diameter of 66cm and its height is 1.98m. The plate it is rolled from is 1.2mm thick and has an E=200GPa. It also has an ultimate strength of 510MPa.



Homework Equations


What is the shear stress?
What is the factor of safety?

Hi mattbreck! Welcome to PF! :wink:

Show us what you've tried, and where you're stuck, and then we'll know how to help! :smile:
 
Hi Tiny Tim,
I've calculated the volume in the drum and I don't know where to go from there to calculate the shear stress.
Thanks,
Matt

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...
