    Equilibrium Weight
AI Thread Summary
The problem involves finding the tensions in three ropes supporting a weight of 1000 N. The participant determined that T1 equals 1000 N and that T2 and T3 must sum to 1000 N for equilibrium. They calculated T2 to be 577 N, leading to T3 being 423 N. The discussion emphasizes the importance of analyzing both vertical and horizontal force components at the junction of the ropes. Understanding these components is crucial for solving equilibrium problems involving multiple forces.

The weight at the end of the rope is 1000 N. Find tensions in T1, T2, and T3.

Homework Equations



Law of Cosine: a^2+b^2-2ab(cosC)=c^2
SOH-CAH-TOA

The Attempt at a Solution



T1 has to be 1000N. I figured T2 and T3 have to add up to the weight of 1000 N. I ended up added the vectors head to tail and found T2 to be 577 N and T3 would have to be 1000-577=423 N since both ropes have to add up to 1000 N to be in equilibrium. I honestly do not have a clue how to do the problem (it was on a test today and it's really bugging me what the answer is or how to even achieve the answer)

Consider vertical and horizontal force components. Start by analyzing the vertical forces acting on the junction of the ropes.
 

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 '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 .
