The motor of a table saw is rotating 3450 rev/min. A pulley attached to the motor shaft drives a second puller of half the diameter by means of a V-belt. A circular saw blade of diameter 0.208 meter is mounted on the same rotating shaft as the second pulley.
a.) The operator is careless and the blade throws and catches back a small piece of wood. This piece of wood moves with a linear speed equivalent to the tangential speed of the rim of the blade. Determine what is this speed?
b.) Compute the radial acceleration of points on the outer edge of the blade to see why sawdust does not stick to its teeth.
