WebYou have a grindstone (a disk) that is 90.0 kg, has a 0.340-m radius, and is turning at 90.0 rpm, and you press a steel axe against it with a radial force of 20.0 N. (a) Assuming the kinetic coefficient of friction between steel and stone is 0.20, calculate the angular acceleration of the grindstone. WebFirst, the machined length per minute is calculated, in this case from the rotational speed and the feed amount. Machined length per minute (l) = n × f = 0.2 × 1100 = 220 mm/min Substitute this into the formula: Tc = lm ÷ l = 120 ÷ 220 = 0.55 (min) × 60 = 33 (sec) The machining time (Tc) is approximately 33 seconds.
