1. The problem statement, all variables and given/known data The carbide tips of the cutting teeth of a circular saw are 8.6cm from the axis of rotation. 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? While the saw is cutting lumber, its angular speed slows to 2400rev/min and the power output is 1.9hp. What is the tangential force that the wood exerts on the carbide tips? 3. The attempt at a solution Would part a be that it's like that because it's not producing any work, there is no friction or any force acting/slowing down the rev/min.? How do I start part b? Before: 4800 rev/min 0hp After 2400 rev/min 1.9hp How would I calculate the tangential forces.? Please and thank you.
