What is one advantage of hydraulic systems in machinery?

Hydraulic systems are known for their ability to generate significant force while maintaining a relatively compact design, largely due to their high power-to-weight ratio. This characteristic allows machines that utilize hydraulic systems to be designed smaller and lighter than those that rely on other forms of power transfer, such as pneumatic systems or manual operation. The high efficiency of hydraulic fluid in transmitting power enables machinery to achieve substantial torque and lifting capabilities without requiring excessive space or weight. Consequently, their compactness does not compromise performance, making them ideal for applications where space is at a premium. This advantage is precisely why the selection of hydraulic systems is common in various industries, including construction and manufacturing, where heavy lifting or precise control is essential. The other options do not reflect the core benefits and typical applications of hydraulic systems, which is why they are not correct.
