Final answer:
The blade of a band saw, while rotating around pulleys, applies a linear force to the table, translating rotational motion into straight-line motion along the cutting path.
Step-by-step explanation:
The blade of a band saw rotates in two pulleys, which applies a linear force to the table. Although the blade itself is rotating around the pulleys, the motion that it imparts on the material being cut is linear as the blade moves in one continuous direction along the cutting line. This motion can be compared to how reciprocating motion uses the rotation of a motor to produce linear motion up and down or back and forth, similar to the operation of a reciprocating saw. The rotation of the saw blade does not create a rotational force on the material being cut because the material does not spin but is instead pushed or pulled straight through the blade's path.
