. What is the formula for the torque on the turntable in terms of tension T in the string and the lever arm distance 1'? . What is the tension in the string if the turntable is held xed, with the mass hanging from the pulley (i.e., the mass is stationary)? . When the mass is falling, what is the tension in the string? Use Newton's second law to determine the tension T in the string as a function of m, the falling mass, 9, the acceleration due to gravity, and a, the linear acceleration of the falling mass.
