Consider the following apparatus called a circular force table: You will be given the values of 3 masses and their corresponding locations based on a circle rotation (see attached spreadsheet). Calculate the location and mass of a 4th mass that will result in static equilibrium for the system. Once your calculations are made, you have ONE CHANCE to physically test your prediction. GOOD LUCK!!! Show all relevant information and calculations. pulley tpin chords pan Analysis questions: 1. How does friction factor into this activity? Explain where friction might be occurring and how it affects the results. 2. What changes if the table is not level? Explain with the use of a FBD. 3. How does this investigation relate to Newton's first law of motion? Explain by starting with a clear description of this law. 4. The diagram below shows a 25 kg mass that is hanging in static equilibrium. Determine the values of each force of tension. Show all calculations. 25 5.
