A door wedge is jammed underneath a door to hold it open. Is the wedge more effective if you place it near or far from the hinges? Why?
More eefective far from hinges. Torque causing rotation depends on force and point of its applcation from the axis of rotation. bigger the torque farther the point of application of force.

When you push a door closer to the hinges, why does it open more slowly? because you are closer to the center Now choose from one of the following options Why? a) It opens slowly, because the lever arm is shorter so the torque is large b) It opens slowly because the lever am is longer so the torque is large. c It opens slowly, because the lever asi is shorter so the torque is less. Comes from 9.2 The...
When opening a hinged door, the handle is usually on the side of the door farthest from the hinges. Rank the difficulty of opening the door if you were to push or pull on the following locations on the door: Hardest To Open Easiest Open 1. As close to the hinges as possible 2. the center of the door 3. The edge farthest from the hinges
Please help Imagine making a heavy door swing open by giving it a brief hard push. First, you push at its center, "push I " in the diagram Then you push near the edge, "push 2." Both pushes are equally hard akd last the same time. Which push is more effective at making the door swing open? Why? Again, lets compare the effectiveness of two pushes. This time, both pushes are applied to the same spot on the door. But...
If a force of 2.00 N is needed to open a 70.0 cm wide door when applied at the edge opposite the hinges, what force must be applied to open the door if you push against the door 40.0 cm from the hinged side?
Josh's office door is 0.82 m wide, 6.0 cm thick, and 2.10 m high. The door has a mass m = 15.0 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 at rest, the door closer exerts a torque Γ = 4.50 N m. What is the smallest force that you need to apply to the door to hold it open? Enter your...
[LEVER ARM] You open a door by pushing at a right angle to the door. Your friend pushes at the same place, but at an angle of 55° from the perpendicular. If both you and your friend exert the same torque on the door, how do the forces you and your friend applied compare?
d L Why are door stops there? [6 pt). A well designed door stopper anchored to a wall is placed in such a way as to minimize damage to the door hinges. Instead of placing the door stop at the maximum door length (to apply the maximum torque), it is better to place it at a closer distance d <L from the hinges, so that the hinges do not need to provide a horizontal force to stop the door. For...

Try placing your hand at the middle of the door and push to open it. Will you require more or less effort than when you open it using the handle? why so?
Propose two 2 strategies to open the door to publicpublic-private partnerships. Explain the main reasons why your proposed strategies would be effective. give 3 examples in which you have taken a leadership risk during the past year.
