Why is mechanical energy called mechanical energy?
Because it's the sum total of the energy found in a mechanical system: in other words, the motion or position of an actual object.
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.
Does a change in entropy occur in purely mechanical motion?
Yes, changed in entropy refer to changed in mechanical motion. Entropy is a measure of the number of specific ways in which a thermodynamic system may be arranged, commonly understood as a measure of disorder.
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.
Why do mechanical systems need an external energy source in order to maintain motion?
Because they need a source of power for example a car needs petrol
What system Directly causes mechanical motion.?
Muscular
What body system Directly causes mechanical motion?
Muscular
What is relative equilibrium?
sort of trajectory, solutions of eqaution of motion of a mechanical system,

What is a thermal actuator?
A thermal actuator is a mechanical system that uses thermally induced contraction and expansion of materials to create motion. It basically converts energy into motion.

Yes, changed in entropy refer to changed in mechanical motion. Entropy is a measure of the number of specific ways in which a thermodynamic system may be arranged, commonly understood as a measure of disorder.
How is a pulley important?
Pulleys are used to change the direction of an applied force, transmit rotational motion, or realize a mechanical advantage in either a linear or rotational system of motion.
What directly causes mechanical motion?
The application of HEAT, in any of it's Forms; heat to overcome Inertia.
An example of a mechanical system?
An example of a mechanical system is a simple pendulum. The pendulum consists of a mass (bob) attached to a fixed point by a rod or string. When the pendulum is displaced from its resting position, gravity and inertia create a harmonic motion back and forth.
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.
What is structural constraints?
Structural constraints are set in place by a system or organization. This is based on rules that are to be followed as directed by the organization.
