this is simple, 65% is larger and greater because, 0.6 is a tenth when 65 is a ten and a unit.

When the efficiency of a simple machine is 85 percent, it means that 85 percent of the input work is converted into useful output work, while the remaining 15 percent is lost due to factors like friction and heat. This efficiency percentage gives an idea of how effectively the machine is performing its intended task.

No, a simple machine with less output work than input work is said to have less than 100 percent efficiency. Efficiency is a measure of how well a machine converts input work into output work, with 100 percent efficiency meaning that all input work is converted to useful output work.

so wut exactly is ur question?

Friction between moving parts can cause energy loss in a simple machine, reducing its efficiency below 100 percent. Additionally, external factors such as air resistance or other forms of resistance can also contribute to energy losses in a simple machine.

Efficiency % = (work out / work in) * 100 (Work = force * distance)

Efficiency % = (work out / work in) * 100 (Work = force * distance)

Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.

Factors that can affect the efficiency of a simple machine include friction, mechanical losses, wear and tear, misalignment, and material properties (such as strength and durability). Proper maintenance and lubrication can help improve efficiency by reducing these factors.

In that case, the efficiency is said to be 1 - or equivalently, 100%.

The transmission lever is very simple and there is no friction.

Increasing the efficiency of a simple machine means that it requires less input work to produce the same output work. This results in less wasted energy and ultimately allows the machine to do more work with the same amount of input.
