A fixed single pulley that is used to lift a block does what?

The choices are:A. Doubles the force required to lift the blockB. Decreases the force required to lift the blockC. Makes the block easier to lift by changing the direction of the force needed to lift it.D. Decreases the force required and changes the direction of the force required

Will the force applied to lift a brick reduce if you use pulleys?

yes, pulley will help IF not the if YOU USE COMBINE TWO OR MORE PULLEYS. Yes, using a pulley or a system of pulleys will reduce the force needed to lift a brick (or anything). HOWEVER the distance that the rope (or whatever effects the pulley system) has to now travel further so that the energy required to lift the brick through an equal height is always the same.

What is the formula for hydraulic lift?

Force (load) = Pressure X Area

How does a lift work?

The pulley in the mechanical device work together to make the lift move up and down. Counter weights.

What simple machine reduces the amount of effort needed to lift a heavy object?

Lever Hoist

What forces are acting on a helicopter when it is still?

When a helicopter is still, the main forces acting on it are gravity pulling it down, and the thrust generated by the rotor blades pushing it up. These forces are balanced, resulting in the helicopter hovering in place.

What science concepts are involved in helicopter flight?

Helicopter flight involves principles of aerodynamics, including lift and drag. The main science concepts at play are Bernoulli's principle and Newton's third law of motion. Bernoulli's principle explains how differences in air pressure above and below the rotor blades create lift, while Newton's third law states that for every action (downward force of the blades), there is an equal and opposite reaction (upward force of the helicopter).

How does a helicopter get its lifting force?

A helicopter gets its lifting force from the rotation of its main rotor blades. As the rotor blades spin, they create a pressure difference between the top and bottom surfaces, generating lift that enables the helicopter to become airborne. The angle of the rotor blades can be adjusted to control the amount of lift produced.

How much force is needed to lift a weight fo 200n?

The force needed to lift a weight of 200N would be 200N. This is because the force needed to lift an object against gravity is equal to the weight of the object itself.

Why force is needed to lift a bag?

Force is needed to lift a bag because the bag has mass, which causes it to experience the force of gravity pulling it down. By applying an upward force greater than the force of gravity, the bag can be lifted against gravity.

A movable pulley reduces the amount of effort needed to lift a lode by making what change?

A movable pulley reduces the effort needed to lift a load by changing the direction of the force required to lift the load. By pulling down on one end of the pulley system, the load is lifted up with less force needed due to the mechanical advantage gained from the pulley's design.

When a helicopter is a stationary the blades on both sides of the rotor give the same lift?

Yes, when a helicopter is stationary, the blades on both sides of the rotor produce equal lift. This is necessary to balance the helicopter and keep it hovering in place. The main rotor provides lift by spinning rapidly and creating an upward force that counteracts gravity.

How can you decrease the amount of force needed to lift a load with a lever?

You can decrease the force needed to lift a load with a lever by increasing the length of the lever arm. By moving the pivot point or fulcrum closer to the load, you can reduce the amount of force required to lift the load.

How does a helicopter stay in the air?

A helicopter stays in the air by using its main rotor blades to generate lift, which counteracts gravity. The rotor blades create lift by spinning rapidly and pushing air downward. This lift force allows the helicopter to hover or move in different directions.

Why does a moveable pulley reduce the effort force?

A moveable pulley reduces the effort force needed because it changes the direction of the force applied. By pulling down on one end of the rope attached to the pulley, you can raise the load with only half the force needed to lift it directly.

Does the position of the fulcrum affect the force necessary to lift a weight?

Yes, the position of the fulcrum affects the force required to lift a weight. Placing the fulcrum closer to the load reduces the effort needed to lift the weight. Conversely, placing the fulcrum further from the load increases the force needed to lift the weight.

How did the pulley affect the amount of force needed?

A pulley reduces the amount of force needed to lift an object by distributing the load over multiple ropes and wheels. It allows you to lift heavier objects with less effort by changing the direction of the force required to lift the load.
