When a fan is at its highest setting, the fan blade is rotating at 150 Hz. When the fan is turned down to its next lowest setting, the fan blade uniformly decelerates at 12 cycles/s until it reaches 60 Hz. Through how many cycles does the fan blade rotate over this interval? a. 125 cycles b. 240 cycles C. 374 cycles d. 512 cycles e. 788 cycles

Stress transformation

The term stress indicates the measure of internal forces that develop due to an external force's application on an object. When a specific external force is applied to an object, internal stress generates in the material. The value of stress can obtain by taking the ratio of the externally applied force and cross-sectional area of the object. There are different types of stress depending on the type of external force.
