    Cable Statics
AI Thread Summary
The discussion centers around a statics problem involving a crate and the forces acting on it. The participant identifies three forces: the weight of the crate and the two tensions in the cables. They confirm that the gravitational force is equal to the sum of the vertical components of the tensions. Clarification is provided that no additional forces are acting on the crate. The conversation concludes with the participant expressing gratitude for the confirmation.

Homework Equations


Sum of x and y forces = zero
Sum of moments about any point = zero

The Attempt at a Solution


By looking at the portion of the string under the crate, there are 3 forces acting on it, namely the two tensions at the side and the weight of the crate. Hence I deduce that the gravitational force of the crate acting on the string is the sum of the two vertical components of the tensions.

Can anyone tell me if I'm right or am I missing out on any forces?

Please help, thanks much!

You are correct. Next you'll have to use a little trig to find the angle that the cables make.
 
oh i got the angle already, I was just confused as to whether there were any more forces acting on it. thanks for the clarification!
 

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...
