Determine the tension in cable BC and the reactions at A.

AI Thread Summary
To determine the tension in cable BC and the reactions at point A, the problem involves analyzing the 400N weight of member AB, which is positioned at its midpoint along a 3m length. The discussion highlights uncertainty about whether to apply the sum of all forces or to incorporate moments into the solution. It is suggested that the reactions at point A consist of a vertical force acting upwards and a horizontal force directed to the right. The approach to solving the problem may require a combination of static equilibrium equations. Understanding these forces and moments is crucial for accurately calculating the tension and reactions involved.

Homework Statement


The 400N weight of member AB acts at its midpoint. The length of member AB is 3m. Determine the tension in cable BC and the reactions at A.


Homework Equations


m=rxf? maybe
simple force equations

The Attempt at a Solution


Not sure whether to use sum of all forces to equal 0 or to add the concept of moment into this problem.

Also for the reactions at A, according to my textbook, it looks like a triangle with a pin on it so I am assuming reactions at A would only have a vertical force (pointing up; normal) and also and force coming from the left, pushing right at point A.
 

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...
