AI Thread Summary
The discussion revolves around the challenges faced in solving a wrench reduction problem, specifically regarding the calculation of forces and moments. The user typically finds the resultant force (F_r) and then computes the moments (M_r) about a specific point, decomposing M_r into components. They provide specific calculations for F_r and moments about point A but express uncertainty about the next steps and whether their approach is fundamentally flawed. The user seeks guidance or constructive criticism to clarify their conceptual understanding. Overall, the conversation highlights the complexities of wrench reduction in mechanics.

This one is really discouraging me. It looks sooooo easy since the forces are each in one direction

The way I have usually handled these as a procedure is: Find F_r and then find M_r about some point and then decompose M_r into components that run parellel and perpendicular to F_r. Then I can usually find P(x,y)

If I were to move everything to point A I would have:
F_r=500i+300j+800k
And I would also have to find the couple Moments about A:
M_x_A=4(800)=3200
M_y_A=0
M_z_A=6(300)=1800

I am just unsure where to go from here? Or is this all wrong altogether?

I have done this one over soooo many times. I am clearly missing a crucial conceptual point. ANY hints or criticism would help.
 
Well Good Morning!
 

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...
