The carbide tips of the cutting teeth of a circular saw are 8.6 cm from the axis
Question:
(a) The no-load speed of the saw, when it is not cutting anything, is 4800 rev/min. Why is its no-load power output negligible?
(b) While the saw is cutting lumber, its angular speed slows to 2400 rev /min and the power output is 1.9 bp. What is the tangential force that the wood exerts on the carbide tips?
