*PLEASE HELP WITH #3 and #4*

You are in a class titled Introduction to Artistic Expression, and your final project must be completed in class. You know that you will be given one object and one board to work with to create a displays.  You also know that you must arrange the object on the board so it balances on a tiny pedestal.  Once completed, the display will be a single object resting on a board balanced on top of a pedestal.

  1. Draw a picture for the single mass model. Select a coordinate system.  Identify and label the quantities you can measure in this problem, such as masses and lengths. The unknown quantity in this problem is the locations of the mass in relation to the balance point.  
  2. On your picture, identify each force on your system.  Draw a free-body diagram of the board that includes distances from the balance point for each force. For now, identify an arbitrary balance point for the system. (This is OK, you will use the condition of equilibrium to make the correct choice in a bit.)
  3. Write down an expression for the net torque on the system. What is the net torque when the system is in equilibrium?
  4. How many unknowns are there in your torque equation? Since we have too many unknowns to solve this equation, we need to add an additional constraint. Make the object mass twice the meter stick mass.
  5. Solve the equation to find the equilibrium location of the mass.
