What is the force acting in a perpendicular direction?

HELLO THERE! When force is acting on a moving body in perpendicular direction, Work done by the force will be zero, because W = F.S cos θ, where θ = 90, and cos 90 = 0, so W = 0. So, there will be no change in the magnitude of velocity (or speed) of the body.

How do you determine the direction of the hinge force?

The direction is perpendicular to both the radius from the axis and to the force. It is done by the right hand rule direction along the axis of rotation.

Where should you push on a door to apply the most torque when opening the door?

If you exert a force at the hinge, the door will not move; the easiest way to open a door is to exert a force as far from the hinge as possible, and to push or pull with a force perpendicular to the door. This maximizes the torque you exert.

How does hinge force act?

When a mass is on a horizontal surface, the reaction force acts normal to the surface, in the direction of the line of action of the gravitational force exerted by the mass on the ground. In this case, thus, you would expect the hinge to exert a force into the rod, because this is normal to the wall.

What are the effects if forces acting on a moving body in a direction perpendicular to the direction of motion?

As force is perpendicular to the direction of motion there will be no change in speed of the body but the direction of motion of the body will keep on changing continuously .

What is the work done when force is perpendicular to the direction of motion?

Work is zero if the force is perpendicular to the motion.

Why is it easier 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.

What is a hinged rod?

EXPLORATION 10.10 – A hinged rod. The rod is attached to a wall by a hinge at one end. As shown in Figure 10.24, the angle between the rod and the string, which holds the rod in a horizontal position, is 30˚.

Does it matter if you push at the same height as the hinges?

b) It does not matter at what height you push. The torque depends on only the magnitude of the force applied and the perpendicular distance of the force’s application from the hinges.

What happens if you push in the middle of the door do you need more or less force?

First of all, the larger the force, the more effective it is in opening the door—obviously, the harder you push, the more rapidly the door opens. Also, the point at which you push is crucial. If you apply your force too close to the hinges, the door will open slowly, if at all.

What is hinge physics?

A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them.

Is there a reaction at a hinge?

A hinge has two unknown reaction forces and two unknown reaction moments along the coordinate axes that are perpendicular to the axis of the hinge. There is also a reaction force along the axis of the hinge (i.e. does not slide along the z-axis). Thus, the hinge may only rotate about this axis.
