Linear transmission of motion
Linear transmission mechanisms transmit motion and force through a motor to another point.
A lever is a rigid bar that turns around a point called a fulcrum. At one end of the bar, force (F) is applied to move a resistance or load (R) at the other end of the bar.
There are three types of levers 🙋
The fulcrum is between the force and the resistance
The effect of the force applied is increased or decreased
The resistance is between the fulcrum and the force
The effect of the force applied is always increased ( d > r )
The force is between the fulcrum and the resistance
The effect of the force applied is always decreased ( d < r )
