As shown in Figure, I want to calculate the torque at a shaft parallel to the motor shaft. Both shafts are attached through 2 pulleys and belts as shown in Figure. For maintaining a similarity between my application* and solid works model, I have attached an imaginary motor to smaller pulley A..

Application: I have an exercise bike (stationary) with the same kind of arrangements. I want to calculate the torque generated by pedal force at the pulley other than the pulley which is directly connected to Pedal. I want to find out whether the torque values are the same at both pulleys or not?
