Question

give two examples of mechanical forces

Answer 1

An example of a mechanical force is someone pushing a door. The person’s hand makes direct contact with the door and applies the force to it. By contrast, if the door is not perfectly level, gravity pulls it in one direction or the other without making direct contact with it. Mechanical forces can travel through the air as the air functions as a medium, but natural forces can travel through space, which is not a medium.

another example, in engine cylinder after combustion the power pushes the piston down and crankshaft rotates. here combustion is chemical force and rotates of crankshaft is mechanical force.
