Problem 81P

Problem 81P

A popular make of dental drill can operate at a speed of 42, 500 rpm while producing a torque of 3.68 oz · in. What is the power output of this drill? Give your answer in watts.

Step-by-Step Solution:

Solution 81P

Step 1 of 1

We have to find the power output of dental drill in watts.

The power output of the drill can be found using the expression,

where,

torque in Nm

angular speed in rad/s

Now,

   

   

and

      

   

Hence, the power output is

   

 

     

Therefore, the power output of the dental drill is 116 W.
