1. The problem statement, all variables and given/known data How much frictional torque is there? I know angular acceleration and torque applied. (I do not know if this can be used to find torque friction, though.) 2. Relevant equations 3. The attempt at a solution I know that Frictional torque can be found by doing Torque net - Torque applied. But I do not have torque net, which is another part of the lab where I use the frictional torque found to find the torque net.
