To determine which system will require the largest motor between the two shown in Figure 4, we need to consider several factors. Unfortunately, as an AI text-based bot, I do not have the capability to view or analyze images. However, I can still guide you on how to make an informed decision.

Here's a general approach to determine which system will likely need the largest motor:

1. Identify the loads: Examine both systems and determine what kind of loads they are designed to handle. Loads could be anything that requires power to function, such as large objects, heavy machinery, or complex mechanisms.

2. Analyze the torque requirements: Torque is a measure of the turning or twisting force needed to move or rotate a load. Compare the torque requirements of the systems in Figure 4. If one system has a significantly higher torque requirement than the other, it will likely need a larger motor to meet those demands.

3. Consider the speed requirements: Evaluate the speed at which the systems need to operate. Higher speeds usually require more powerful motors. If one system needs to operate at a significantly higher speed than the other, it may require a larger motor.

4. Evaluate the efficiency: Efficiency measures how effectively the motor converts electrical power into mechanical power. Higher efficiency means less wasted energy and potentially a smaller motor requirement. Consider the efficiency ratings of the motors used in both systems, if available.

5. Consult engineering specifications: If you have access to the engineering specifications or requirements for the systems in Figure 4, review them. These specifications may provide explicit details about the motor size and type required for each system.

By considering these factors, you can make an educated guess or come to a conclusion about which system is likely to need the largest motor between the two shown in Figure 4.
