at the wiper linkage that is at the base of the wiper arms there is a retainer clip that has broken allowing the linkage from the motor to not move the arms. This happened to me on an 1989 Ford pick-up once. It was a pretty easy fix once I figured out the right timing of the linkage.

Rotor blades.
Steam turbine is comprising of stages, number and size of the stages depands upon the break horse power of the turbine. The stage has set of moving and fixed blades. The moving blades are attached to the rotor while the stationary blades is called Diaphragm. The diaphragm guides the steam to glide over the moving blades for producing rotary motion.

In an impulse turbine, the stage is a set of moving blades behind the nozzle. In a reaction turbine, each row of blades is called a "stage." A single Curtis stage may consist of two or more rows of moving blades.

The kinetic energy of the air molecules in the 'wind' is transferred to the blades of the windmill as kinetic energy of the moving blades of the windmill.
That bend is needed in order to change rotational motion of the blades into the linear motion of moving air.

A tractor employers blades that revolve to cut grass while moving.
