Which of the two systems in figure 4 do you think will need largest motor

To determine which of the two systems in Figure 4 will require the largest motor, we need to consider a few factors:

1. Gear Ratio: Check if either system has a different gear ratio. If one system has a higher gear ratio, it will generally require a smaller motor as the gears provide mechanical advantage.

2. Load: Evaluate the load being moved or operated by each system. If one system has a heavier load to move, it will typically require a larger motor to provide enough power.

3. Friction and Efficiency: Assess the level of friction and efficiency in each system. If one system has more friction or lower efficiency, it will demand a larger motor to overcome these factors.

4. Speed: Consider the speed requirements for each system. If one system requires higher speeds, it may necessitate a larger motor to generate the necessary rotational energy.

By analyzing these factors, you can determine which system will likely need the largest motor. It is important to note that without specific information about the systems in Figure 4, it is difficult to provide a definite answer.
