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
 

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'

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...
