MHB Mechanics-Conical pendulum, circular motion

AI Thread Summary
A particle weighing 100 grams is connected to two strings of lengths 30 cm and 50 cm, with point A positioned 30 cm below point B. The discussion focuses on determining the range of angular velocities that allow the particle to move in horizontal circles while keeping both strings taut, with gravity set at 10 m/s². The calculated range for the angular velocity is between 5 and 9.14 radians per second. Key considerations include the equilibrium of vertical tension forces against gravity and the horizontal tension providing the necessary centripetal force. Understanding these dynamics is crucial for solving the problem effectively.

A particle of 100 grams is attached by two strings of lengths 30cm and 50cm respectively to points A and B, where A is 30cm vertically below B. Find the range of angular velocities for which the particle can describe horizontal circles with both strings taut. Take g as 10m/s^2

Answer
Show diagram if possible
5<angular velocity<9.14

Welcome to MHB, dragonoid! :)

What is your question?
Can you show some of your thoughts?

Note that the range is limited by the fact by the boundary condition where either there is just no tension on the upper string, or there is just no tension on the lower string.

We will need:
  1. equilibrium between the vertical component of the tensional force and the force of gravity,
  2. the horizontal component of the tensional force equal to the required centripetal force.
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
Is it possible to arrange six pencils such that each one touches the other five? If so, how? This is an adaption of a Martin Gardner puzzle only I changed it from cigarettes to pencils and left out the clues because PF folks don’t need clues. From the book “My Best Mathematical and Logic Puzzles”. Dover, 1994.
