How would the force needed to open a door change if you put the handle in the middle of the door?
If the doorknob were moved to the middle of the door, it would take twice as much force to open it than if it were at the edge of the door. With the mass of the door being equal. Moment = the force to open the door times the distance to the center of the hinges. If the distance were cut in half it would take twice the force to keep the equation true.
When you pull a door open if the force the door exerts on you is equal to the force you exert on the door why dont you move?
-- The door's force on your hand is not necessarily equal to the force of your hand on the door. If it were, then the sum of the forces at the hand-door interface would be zero, and there would be no acceleration there to open the door. The point where the action and reaction are equal is the point in your arm where the muscle is anchored to the bone. Or better yet, between your feet and the floor. -- You weigh more than the door weighs. So equal forces on you and on the door produce more acceleration and more speed of the door than of you. (For the same reason that the rifle recoils at a slower speed than the bullet's muzzle velocity.) -- If you were on hinges, or on ice skates, then you would move too. The door's mounting arrangement is built in such a way that it's more free to move than you are, when your feet are planted and you're using your legs to keep you upright.
Can you open the doors of a submerged vehicle?
Not without a tremendous amount of force. To be able to open the doors with a reasonable amount of strength, open the window to let water in, equalizing the inner and outer pressures on the door. then you can open the door.

Effort force is a force used to move an object over distance.Which ball will bounce higher lacrosse ball or tennis ball?Read more: Which_ball_will_bounce_higher_lacrosse_ball_or_tennis_ball

Why are door handles placed towards the corner of the door?
The door-handle is usually on the opposite side of the door from the hinges to give the best leverage on the door, ie you need less force to pull the door open. You are producing a torque on the door. (Torque is a rotational force). Essentially, as you apply a force to rotate something, less is needed to cause rotation if you apply that force further away from the center of the rotation (in this case, the hinges). Try to push open a door by pushing on the door very close to the hinges, and you will find that it is quite difficult.
What friction is used while opening a door?
While opening the door you do work to generate a moment of inertia that opens the door. The moment of inertia= force applied x perpendicular distance between the point of application of force and the axis of rotation. The greater the perpendicular distance the easier it is for you to open the door, i.e. a less amount of force can be applied to open the door. I hope this was useful.
Why cant you open a door by pushing on its hinged side?
to open the door toque must be applied on it. torque = force * perpendicular distance when the door is pushed at the hinge perpendicular distance is zero. Hence, it can not be opened
