it is you get to live a regular life without sooo much work.
A regular pencil is considered an instrument, a mechanical pencil may be considered a simple machine , in that it has moving parts that rotate, and move up and down.
A ballpoint pen is just a pen with a cap. A regular pen is one that clicks. They both work the same though.
because if the pen vibrated then the seismograph wouldn't work and it would defeat the purpose. the machine only works if the pen is still. if the pen is still the machine will guide it by the heartbeat lines the pen creates.

No. The classic simple machines are: Lever Wheel and axle Pulley Inclined plane Wedge Screw Using the pen has no mechanical advantage, other than in a ballpoint pen where the roller bearing reduces friction, but is primarily intended to produce an even ink application.
The ball is a roller bearing. It reduces the friction as the pen point is slid across the paper. Quill pens use a rounded nib, but the ink distribution can be uneven.
He didn't have a pen.
An airplane is not a simple machine. A lever is a simple machine. A wheel is a simple machine. Any machine that can be described by a mathematical formula is a simple machine.
It is a wheel. The ball rolls across the surface, instead of scraping across as a pencil or nib pen would.
Can you change a regular washing machine into a portable to hook up to the kitchen sink
A pulley isn't a kind of simple machine, it is a simple machine
