Help Required: Calculate Tensile & Shear Stress for 200mm2 Area

  • Thread starter Thread starter Malawaki
  • Start date Start date
AI Thread Summary
The discussion revolves around calculating tensile and shear stress for a component with a 200mm² cross-sectional area subjected to a tensile force of 40kN. The tensile stress is calculated as 200 MN/m². There is confusion regarding the maximum shear stress, with the participant questioning whether it can be zero when only a tensile force is acting. They note that shear stress can exist in components even when tensile stress is present, and they seek clarification on whether the calculated tensile stress can also represent the maximum shear stress. The inquiry highlights the complexities of stress analysis in materials under different loading conditions.

Homework Statement


Hi i have the following question a component of 200mm2 cross sectional area is subject to a tensile force of 40kn Determine the tensile stress and the maximum shear stress that exist within the component ? I can work out the shear but how can i work out the maximum Shear ?


Homework Equations


stress = Force
area


The Attempt at a Solution


stress = 40,000
0.0002

= 200MN/m2

The problem i have is calculating the other stress any help would be gratefully appreciated
 
Physics news on Phys.org
If there's only a tensile force acting, surely the shear stress is 0?
 
I don't know it may but i always thought shear stress was present in all compoenets and in fact in a tenisle stress test the test specimen did not actually fail in tensile stress but in shear stress. I may be looking to far into the question can the tensile stress i have calculated also be the maximum shear or not ?

Thanks in advance

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...
