In analyzing the efficiency of a wheel and belt system, the metric commonly assessed is the energy transmitted. This assessment is crucial because it allows for understanding how much energy from the motor or driving mechanism is actually being used to perform work versus how much is lost due to friction, slippage, or other inefficiencies in the system. By focusing on energy transmission, one can evaluate the effectiveness of the system in converting input energy into useful output energy, which is vital for optimizing performance.

Evaluating other factors like force output, revolution speed, and torque produced might provide insights into different aspects of the system's operation. However, they do not directly give a comprehensive picture of overall efficiency in the same way that analyzing the total energy transmitted does. Energy transmission encapsulates the energy losses and gains throughout the entire process, making it the most relevant metric for understanding system efficiency in a wheel and belt setup.
