As the shaft is heated, the dial indicators will climb - indicating that the amount of the bend is increasing, temporarily. This is the desired result, even though it seems counter-intuitive. It is important to get a initial feel for the responsiveness of the shaft to bend reversal. During the first spot heating cycle, heat the shaft until the ...

Annealing can be performed at the mill, and the material received at the plant ready to be machined, or it can be done in-house to facilitate machining. There are many different types of annealing that can be performed. But in all cases, the primary reason for annealing is to soften the part and increase the ductility for forming or …

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
