How does friction impact the amount of mechanical energy produced by a machine?

Well friction is the opposing force to any object who is doing work against another. So the force needed to overcome friction costs more energy than required thus decreasing efficiency of the machine.

Friction in a machine can reduce the mechanical energy produced by increasing the amount of energy lost as heat. Friction between moving parts causes resistance, which converts some of the mechanical energy into thermal energy. Minimizing friction through lubrication and proper maintenance can help increase the efficiency of a machine and maximize the amount of mechanical energy it produces.

Explain why the amount of work that a machine does is less than the amount put into the machine?
Output work is always less than input work.
The amount by which a machine multiplies an input force is called?
mechanical advantage
What are factors that limit the efficiency of a machine?
Friction is the most common factor affecting the efficiency of any machine.
What is the maximum amount of mechanical energy that can be converted to heat?
Why should there be a maximum? If there is friction, ALL the mechanical energy will eventually be converted to heat.
Why would machines work better without friction?
The smaller amount of friction a machine has, the more efficient it becomes.
What can be done to increase the efficiency of the machine?
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.
Why is the amount of that a machine does is less than the amount put into the machine?
In such a machine, the remaining energy is wasted to friction

A kitchen blender transforms electrical energy into mechanical energy Why is the amount of mechanical energy produced less than the amount of electrical energy used?
Losses are due to inefficencies of the motor, and friction on moving parts.
Why oil and grease is applied between different parts of machine?
Oil and grease can reduce the amount of friction, making it easier for parts to slide against one another, and reducing the amount of heat produced.
The amount by which a machine multiplies an input force is called?
mechanical advantage

What are factors that limit the efficiency of a machine?
Friction is the most common factor affecting the efficiency of any machine.
What is maximum friction?
the terminal amount of friction possibly produced between two interacting inanimate objects. this is where we get brake horsepower from.
What is the amount by which a machine multiplies an effort force is called?
mechanical advantage _ l l -
The efficiency of the wedge is low because of?
friction or The mechanical advantage is greater for thinner wedges. However, the efficiency is low because of the large amount of friction.
