QUESTION:

(a) When opening a door, you push on it perpendicularly with a force of 55.0 N at a distance of 0.850m from the hinges. What torque are you exerting relative to the hinges? (b) Does it matter if you push at the same height as the hinges?

ANSWER:

Solution 1PE Step-by-step solution Step 1 of 3 (a) Torques depends upon magnitude of force applied and the perpendicular distance of the force’s application from the hinges. Here perpendicular distance is 0.850 m and the force F is 55 N. Torque exerting relative to the hinges is,
