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
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
