shown in the image is a door with marked hinges and four labeled doorknobs. A is closest to the hinges. B and D are equidistant horizontally from the hinges, but D is located higher on the door. C is furthest from the hinges. Simple 8:16 AM docs.google.com Shown in the image is a door with marked hinges and four labeled doorknobs A is closest to the hinges Band D ane equidistant horlizontally from the hinges but D is located higher on the door C is furthest from the hinges An equal pulling force, F.is applied to each door knob perpendicular to the hinge to doorknob line Door Hinges Created for Albert.lo.Copyright 2016.A right reserved Which of the following correctly ranks the applied torque to each doorknob from greatest torque to least torque magnitude only A>B>D>C O C>B>D>A

Explanation / Answer

Ans: C>B=D>A

Torque is given by the relation,

T = Fd

where d is the distance of the applied force from the hinge.

So, torque is directly proportional to the distance and hence the ranking.
