Statics Engineering Problem Involving Beams

AI Thread Summary
The discussion revolves around a statics engineering problem involving beams, with the original poster seeking feedback on their solution. They provided links to their homework and attempted solutions for review. Key points include inquiries about the correctness of their solution and the presence of a bending moment to the left of R1. Another participant confirms the existence of a bending moment due to the beam's loading and expresses confidence in the calculations up to M3. Overall, the thread focuses on collaborative problem-solving in engineering statics.

Anybody?
 
Is your solution incorrect? Is there a bending moment the the left of R1?
 
I am not a civil engineer but I read that the bending moment is the integral of the sheer force diagram. It looks like this is what you have done. I see there is a bending moment to the left of R1 due to the loading of the beam.
 
I checked your numbers up to M3 and I think you are doing good.
 
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 .
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...
