Archeologists in Egypt are attempting to open a 2.57-m-wide door in the tomb of Tutankhamen. Miles, one of the rookie archeologists pushes perpendicularly on the door with a force of 894 N.
(a) How much torque does Miles exert on the door?
(b) As the door opens, Miles continues to push with the same force, but is at an angle of 30.0° to the face of the door. How much torque does Miles apply to the door?
(c) What could Miles do to continually exert the same amount of torque on the door?
