What configuration do tandem type actuators use?

The correct answer describes the tandem type actuator, which uses two or more cylinders arranged linearly. This configuration allows for greater force output and extends the range of movement compared to single-cylinder actuators. Each cylinder contributes to the overall function by working in conjunction, enhancing the actuator’s performance in applications requiring higher torque or precise control.

In tandem actuators, the linear arrangement maximizes efficiency and allows multiple stages of movement, which is essential in various mechanical systems where space constraints and performance capabilities are critical. This setup is commonly found in situations involving hydraulic systems, where the actuation is focused on power transfer through multiple stages of cylinders working together, thus providing a robust solution for generating motion.

The other configurations listed may serve specific functions in broader mechanical operations but do not characterize the unique arrangement and operational advantages of tandem type actuators, which are specifically designed to enhance functionality through their linear assembly.
