Question
The motor of a table saw is rotating 3450 rev/min. A pulleyattached to the motor shaft drives drives a second puller of halfthe diameter by means of a V-belt. A circular saw bladeof diameter 0.208 m is mounted on the same rotating shaft as thesecond pulley.a.) The operator is careless and the blade catches and throws backa small piece of wood. This piece of wood moves with a linearspeed equal to the tangential speed of the rim of the blade. What is this speed?
b.) Calculate the radial acceleration of points on the outer edgeof the blade to see why sawdust doesn't stick to its teeth.
Explanation / Answer
you have to divide by radius and not diameter. Answer to part B is 54230.9
