Friction affects mechanical efficiency by reducing the amount of useful work output compared to the input work. High levels of friction can decrease efficiency by causing energy losses due to heat production and surface wear. By reducing friction through proper lubrication and design, mechanical efficiency can be increased.
Friction plays a significant role in mechanical efficiency as it causes energy loss by converting mechanical energy into heat. Minimizing friction through techniques such as lubrication and using low-friction materials can help improve the efficiency of a mechanical system by reducing energy wastage. A well-designed system will aim to strike a balance between reducing friction for efficiency and ensuring that enough friction is present for proper operation.
Friction in pulleys can reduce the efficiency of mechanical systems by causing energy loss through heat generation. This can lead to decreased performance and increased wear and tear on the system. Minimizing friction through proper lubrication and maintenance can help improve the efficiency of pulleys in mechanical systems.
Without friction, some forms of mechanical advantage do not function. In most cases for a mechanical apparatus, a reduction in friction is usually accompanied by an increase in efficiency.
Reducing friction increases the efficiency of movement and decreases the energy required to overcome it. This can lead to less wear and tear on surfaces in contact and prolong the lifespan of mechanical parts.
Friction loss in mechanical systems can be reduced by using lubricants, polishing surfaces, and using bearings. These methods help to minimize the resistance between moving parts, improving efficiency.

Friction is the reason that you can never have a 100% efficient machine. It is the reason that most machine have horrible efficiency.

friction or The mechanical advantage is greater for thinner wedges. However, the efficiency is low because of the large amount of friction.
The assumed efficiency is 100% without any friction
Without friction, some forms of mechanical advantage do not function. In most cases for a mechanical apparatus, a reduction in friction is usually accompanied by an increase in efficiency.
Mechanical Efficiency is the ratio of Actual mechanical advantage to ideal mechanical advantage.Efficiency will be maximum when Actual mechanical advantage equals that of ideal.But practically not possible.Actual mechanical advantage will be less due to friction,heat,deflection etc.avoiding these loses will increase the machine efficiency.
Ideal mechanical advantage is the mechanical advantage when there is no friction. It is the mechanical advantage when the efficiency of the pullefy system is 100%. It is a constant for that system of pulleys. Therfore it is not affected by increasing or decreasing the load. But actual mechanical advantage will be less than this ideal mechanical advantage due to friction. In other words the efficiency will be less than 100 %. If the efficiency is 80%, it implies 20% is wasted due to friction while lifting a load. If we increase the load the friction also increases and hence the efficiency will decrease with the load.
