You try to open a 0.82m wide door by pushing on the end furthest from the hinges and your workmate is pushing back 0.18m from the hinge of the door, how much harder do you have to push to keep you at bay?
Added by Lisa F.
Step 1
The hinge is the pivot; your push is at r1 = 0.82 m and your workmate's push is at r2 = 0.18 m. Show more…

Two children push on opposite sides of a door during play. Both push horizontally and perpendicular to the door. One child pushes with a force of $17.5 \mathrm{N}$ at a distance of $0.600 \mathrm{m}$ from the hinges, and the second child pushes at a distance of 0.450 m. What force must the second child exert to keep the door from moving? Assume friction is negligible.

You are pushing on a door with a horizontal force of 300 N. The moment arm of this force around the hinges of the door is 45 cm (0.45 m). The other person is pushing in the opposite direction on the other side of the door (F1). The moment arm of the other person's pushing force is 55 cm (0.55 m). How large is the force that the other person pushes with if the door is in static equilibrium?

A professor's office door is 0.98 m wide, 1.87 m high, and 4.09 cm thick; has a mass of 20.65 kg; and pivots on frictionless hinges. A "door closer" is attached to the door and the top of the door frame. When the door is open and is at rest, the door closer exerts a torque of 4.06 M·m. What is the least force that you need to apply to the door to hold it open?
