Why it is easier to push and open a door at the end away from the hinge?

As distance increases, torque increases and so the rotational effect increases. Hence, it is easier to push open a door by holding the knob than by pushing closer to the hinge.

Is difficult to close or open a door by applying force at the hinges Why?

We cannot open or close the door by applying force at the hinges. Because the torque of force at the hinges is zero as perpendicular distance is zero. Hence there is no rotational motion.

Why is it more difficult to push a door near the hinges quizlet?

Because of the position that you are pushing the door which is because of torque. Why is it more difficult to push a door near the hinges instead of a as a larger distance from the hinges? Lowering the moment of inertia of the swinging leg. More torque must be applied to alter the object’s rotation.

Why it is easier to open a door?

It is easier to open a door by applying the force at the free end of it because of the larger the perpendicular distance, less is the force needed to turn the body.

Why is it harder to push a door near the hinges?

The reason is due to the effect of Torque. The rotational effect increases when the distance increases. It’s easier to open a door if you hold the knob and push closer to the hinges.

Why is it hard to turn the door near the hinges compared to the end?

As the applied force moves away from the hinge, the process I described in the above paragraph kicks in. The more of the door is on the same side of the force as the hinge, the more inertia that side produces and the slower it accelerates. Again, because the hinge can’t move, it provides an opposing force.

Which force is used to close the door?

There is some frictional force in the door hinge, against that we apply force. The hinge friction is again a contact force.

When someone close the door which force is being applied?

A static torque is one which does not produce an angular acceleration. Someone pushing on a closed door is applying a static torque to the door because the door is not rotating about its hinges, despite the force applied.

How does the string of a yo yo get the yo yo spinning quizlet?

The string pulls on the outside edge of the yo-yo’s spindle and at right angles to the lever arm between the yo-yo’s rotational axis and the point at which the force acts. As a result, it produces a torque on the yo-yo about its rotational axis and caused the yo-yo spinning.

Why is it so important that this cutting location is very near the pliers pivot?

Why is it so important that this cutter be located very near the pliers’ pivot? 12 The closer the wire is to the axis of pliers’ axis of rotation, the less effective any force from the wire is at producing a torque on the pliers and stopping its rotation.

Why is it easier to open a door by applying the force at the free end of it Shaalaa?

(iv) It is easier to open the door by applying force at its free end because the increased perpendicular distance decreases the amount of force required to open the door as the moment of force is the product of force and the perpendicular distance.
