How do you use algebra in a see saw?
The see-saw needs to balance so the force on wither side of the pivot needs to be equal. The turning force is calculated by distance from pivot (in metres) by force. The side with the largest turning force will be lower than the other. If they are equal then the see saw will balance.
How far from the pivot must the 10000 N counter weight be placed in order to balance the load?
To balance the load of 10000 N, the counterweight must create an equal and opposite moment. Moment = Force × Distance. If the load is placed at a distance of 2 meters from the pivot, the counterweight should be placed 2 meters away on the opposite side to balance it.
How do you open a screw type damper?
To open the handle must pull it towards you. The handle has pivot points allowing the door to open in steps.
What acts as the pivot on a wheelbarrow?
The axle is the point about which the wheelbarrow's tray revolves.
What is the balance point of a lever?
fulcrum
The size of the turning effect of a force depends on?
The size of the turning effect of a force, or torque, depends on the magnitude of the force and the distance from the pivot point at which the force is applied. The longer the distance from the pivot point, known as the moment arm, the greater the turning effect produced by the force.
What are the names of the parts on balance scale?
The parts of a balance scale include the beam, the pointer, the pivot point, the pan, and the base. The beam is the horizontal bar where the pans are attached, the pivot point is the central point where the beam rotates, and the pointer indicates balance.
Why you add counter balance to car park barriers?
so that the electric motor lifting the barrier dose not have to work even a 3rd as hard as it would have to in order to lift all that weight it just shifts the pivot point over.
Why can you turn your head without turning your body?
because of a pivot joint that connects the skull to the body.
What is the definition of turning effect?
The turning effect, also known as torque, is the rotational equivalent of force and is a measure of the tendency of a force to cause an object to rotate around a pivot point. It depends on both the force applied and the distance from the pivot point where the force is applied.
How is the long tail used by a kangaroo and a wallaby?
The tail is used for balance and to pivot and turn.
If you put a 300 gram weight in the center on the pivot where would you put a 50 gram weight to balance it?
If you put a 300 gram weight in the center on the pivot, the pivot is already balanced because it has the same amount of grams on each side. Therefore, another 50 gram weight would not help to create balance.
