AI Thread Summary
The discussion centers on a homework problem involving torque, specifically how to interpret the second question related to force applied on a bolt. The key equation mentioned is Torque = Distance * Force, which is crucial for solving the problem. The user believes that the distance refers to the radius and that knowing the torque allows for the calculation of the force. Clarification on the question's intent is sought to ensure accurate understanding and application of the torque concept. Understanding these principles is essential for solving similar physics problems effectively.

Torque = Distance * Force

The Attempt at a Solution



I have a problem with the second question in the problem. What does it mean?

I think it's talking about the force applied on the points of the bolt.That is,it's distance must be the radius and we know the torque.So we can find the force.
 
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...
Thread 'Correct statement about a reservoir with an outlet pipe'
The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
