Question

Expression for net force on a piston of slider crank mechanism

Answer 1

slider crank mechanisms are used for translating rotational motion to reciprocating linear motion or conversely to translating linear motion to rotational motion. Some common examples are piston in car engine, which moves upward&downward, but it has crankshaft to translate the up/down movement (linear) to rotating motion. The other example is in the piston pump or shaping machine that convert rotation motion from electric motor to recicprocating motion in piston ( in pump) and tool (in shaping machine).
