If a simple wheel and axle has an efficiency to raise a mass with a certain effort, what efficiency does it show?

In the context of a simple wheel and axle, efficiency refers to the ratio of the output work (useful work done in lifting the mass) to the input work (the effort applied) expressed as a percentage. In a practical scenario, a simple wheel and axle system can experience energy losses due to friction, material flexibility, and other factors that decrease its performance.

An efficiency of 24.1% suggests that for every 100 units of work input, only 24.1 units are used effectively to lift the mass, while the rest is lost due to inefficiencies in the system. This efficiency might be expected in simpler machines, where the design may not be optimized, and friction plays a significant role.

High efficiencies, such as in the other choices provided, would typically not be achievable in a basic wheel and axle setup. An efficiency of 95.3%, for example, is more characteristic of highly engineered, advanced systems with minimal friction and optimized mechanics. In contrast, the other options present significantly low or high efficiency values that do not align with the practical workings of a simple wheel and axle.

Thus, the efficiency of 24.1% accurately reflects the expected performance for a simple wheel and axle given the real-world considerations of energy
