Problem 27E

Electric Drill.? According to the shop manual, when drilling a 12.7-mm-diameter hole in wood, plastic, or aluminum, a drill should have a speed of 1250 rev/min. For a 12.7-mm-diameter drill bit turning at a constant 1250 rev/min, find (a) the maximum linear speed of any part of the bit and (b) the maximum radial acceleration of any part of the bit.

Step-by-Step Solution:

Solution 27E Problem (a) Step 1: Diameter of the hole d = 12.7 mm -3 Radius r = 6.35mm or 6.35 x 10 m Angular speed of the drill = 1250 rev/min 20.83 rev/s Step 2: Angular speed is given in revolution per minute. It should be converted into rad per sec to solve the problem properly. One revolution = 2 rad Therefore = 20.83* 2 rad = 131 rad/s Step...
