Basic Torque Simulation (C) This simulation consists of a rod to which one to four masses may be attached. Hover mouse over object for its location. Masses as well as axis of rotation can be moved. In each case when you start a simulation for the following questions, reset the values using the icon in the control panel at the left side of the screen. Each question assumes that you have done this. Then set only the values indicated in the question. Attach calculations. 1. What is the mass of the red object? How far is it from the axis of rotation? Calculate the initial torque around the axis, then con?rm by running the simulation. Run the simulation with mass of the rod set to 10kg, then 0kg. How does the mass of the rod effect the motion you observe? Why? 2. Move the red mass to 160 cm le? of the axis. Calculate the initial torque around the axis, then con?rm by running the simulation. Now move the red mass to 161] cm right of the axis. What is the initial torque in this position? How is the direction of torque related to its sign? 3. Add the green mass by clicking on "2" for "Number of Masses" and place it 1200111 to the right of the rotation axis. Calculate the initial torque around the axis, then con?rm by running the simulation. Calculate where the green mass should be in order for the rod to be stationary. Con?nn by simulation. 4. Calculate the missin- values such that the rod is station , then con?rm with simulation.

Using all four masses, what is the maximum positive torque you can produce? Does the rod contribute to this torque? Why? Show calculations.
