Max value of the average normal stress in the links.

AI Thread Summary
The discussion revolves around a homework problem regarding the calculation of average normal stress in structural links. A participant initially questions the area calculation used in the solution, believing it should be based on a single hole's cross-section. They later clarify their confusion, realizing that the problem involves two links rather than one. This insight leads to the correct understanding of the area used in the stress calculation. The exchange highlights the importance of recognizing all components in structural analysis.

Homework Statement


Here is the problem along with the solution:

I am confused about part (a). Why is it that the area used is 2*0.008*(0.036-0.016). If you draw a cross section at just one of the holes, wouldn't that give you the max average stress? So the area used should instead be 0.008*(0.036-0.016)?

Never mind, figured it out! For those who are interested, there are actually two links not one!
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

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...
