What impact ? Is there more to this question so I can help answer ?
The drill press's primary function is drilling, but it can also be used for reaming, countersinking, counterboring, and tapping.
<h3>Before drilling a hole, what tool do machinists use to precisely locate the hole?</h3>
Making a tiny divot with a Spotting Drill will help you find the drill's center when you start a plunge. Some machinists use these tools to chamfer the top of drilled holes, which is a different function for them. When inserted, screw heads sit flush with the component thanks to the chamfer.
<h3>What device do we employ to drill a hole in a part?</h3>
Most often, hole-making tools are related with drilling and drill bits. They offer a quick, simple, and affordable technique to make machined holes. Drill bits operate by axially entering the workpiece and creating a hole with a diameter.

I think since applied force and displacement are perpendicular to each other, then the work done is zero. I hope this helps.
Before anything, if you are lifting the Work value have to be negative, reason is because the formula to the work of the weight is:
*Photo to help you to visualize. (P = Weight Force, F = Force)
If you are lifting, you are exercising a force that opposes the Weight Force, Force up (lifting) and Weight Force down (gravity pulling).
This forms a 180 angle and the cos 180 = -1.
Well let's do the question:
Work (W) = -40 J (Joule = Kg x m^2/s^2)
(negative, explanation given)
Weight Force (P) = 10 N (Newton = kg x m/s^2)
Distance (D) = ?
W = P x d x cos theta
-> -40 = 10 x d x -1
-> -40 = -10 x d
-> d = -40/-10 (J/N)
-> d = 4 meters
A body revolving in circle generally has tangential acceleration if the speed is changing. Since the speed is uniform here, the tangential acceleration is zero.
centripetal acceleration is directed towards the center and is given as
a = v²/r where a = centripetal acceleration , v = speed , r = radius
Since both speed and radius are constant here, the centripetal acceleration is constant and is always directed towards the center.
hence the correct choice is
The acceleration is directed toward the center.
