Are there any situations in which a frictional force can increase the mechanical energy of a system?

No. Friction always acts in the direction opposite to motion,
and dissipates energy.

Is it possible for a frictional force to increase the mechanical energy of a system?
your question is not clear but fro what i could understand, i can tell you that frictional force always opposes motion of mechanical system ( so it would decrease the system's mechanical energy) therefore i can never increase it.
In situations is mechanical energy conserved?
It depends on the situation
What happens to internal energy when mechanical work is done?
Increase.
According to the law of conservation of mechanical energy if the only force acting on this pendulum is gravity the total energy of the system is .?
Conservation of mechanical energy means that the total mechanical energy doesn't increase or decrease over time.Note that in real systems, some mechanical will always be lost due to friction.
What is the difference between a mechanical wave or a transverse wave?
Electromagnetic waves do not lose energy over time. The field of magnetism swaps form and orientation with the electric field and back. There are frictional losses in mechanical waves which dampen them out over time.

Why doesn't the principle of mechanical energy conservation hold in situations when frictional forces are present?
In the case of friction, energy is wasted, i.e., mechanical energy is converted into useless energy, mainly heat.
In which situations is mechanical energy conserved?
A ball is thrown up into the air withough encountering air resistance.
What are frictional losses?
Inefficiencies in a mechanical device related to parts rubbing together such that kinetic energy is turned into heat energy.
In situations is mechanical energy conserved?
It depends on the situation
How do you apply the laws of conservation of mechanical energy in different situations?
di ko alam....
When an ice cube melts does its mechanical energy increase?
yes
What happens to internal energy when mechanical work is done?
Increase.
Do ice cubes melt when their mechanical energy increase?
hecky yeah it does
How do earthquakes release the energy of frictional stress?
Earthquakes release the energy of frictional stress in forms of seismic waves.
When mechanical work is done on a system there is an increase in what?
both temperature and internal energy

Conservation of mechanical energy means that the total mechanical energy doesn't increase or decrease over time.Note that in real systems, some mechanical will always be lost due to friction.
