What else can I help you with?
1 pulley system more efficient then a 2 pulley system?
Efficiency is the proportion of energy usefully used. Using a pulley system does not use less energy it just changes the ammount of force. Pulleys do have a small ammount of friction so having just one pulley would be more efficient. (but not much more)
Would a lever a pulley or inclined plane be least helpful in moving a heavy object?
none of them are the least helpful they all help things move upward except the lever but the most helpful one is the pulley a pulley takes up less space and it goes straight up so u can use less force
Is the 787 Dreamliner's better than the 747's?
Depending on the purpous of the plane, the 787 is more efficient yes, but it can carry less passengers, and less cargo, then the 747.
Why is rocket plane more efficient in the absence of air?
A rocket plane is more efficient in the absence of air because it doesn't have to overcome air resistance, known as drag. This allows it to travel faster using less fuel and achieve higher altitudes without the need for continual propulsion to counteract drag forces.
How an pulley and incline plane change the amount of force needed to move an object?
A pulley can reduce the amount of force needed to move an object by distributing the force over multiple ropes and pulleys, effectively trading force for distance. An inclined plane can reduce the force needed to move an object by allowing it to be raised to a higher elevation with less force over a longer distance.
What causes the output work of a machine to e less than the input work?
Some of the input force is lost due to friction. If you are using a pulley system then there is friction between the rope and the pulley and there is also friction within the ball bearings of the pulley itself. If you are using an inclined plane there is friction between the plane and the object traveling upon it. In a friction-less world the input is equal to the output.
What causes the mechanical advantage of the inclined plane to be less than the lever?
The mechanical advantage of an inclined plane is less than that of a lever because the inclined plane allows for the exertion of a smaller force over a longer distance to move objects up an incline. In contrast, the lever utilizes the principle of leverage to magnify an applied force, making it more efficient in lifting heavy objects.
Why is mechanical advantage of single fixed pulley less than single movable pulley?
because lifes hard
What are five simple machines?
Wedge, Lever, Wheelare the three simple machinesa pulleyclass 1, 2, and three levers like a can opener or a sea saw, and even a wheel barrow.That's easywheel barrow=inclined planeslide=screwwagon=wheel and axleknife=wedgeand there is one more.....a pulley......but I don't know what would be used as that.srry-abby-:) :] (: [:
When Is Friction Useful and When Is Friction Not Useful?
Friction is useful when you are trying to stop a car, but not useful in the pistons of a car's engine (It makes them less efficient).
How does a pulley help us?
A pulley helps us by providing a mechanical advantage, making it easier to lift heavy objects by distributing the force required over multiple ropes or cables. By using a pulley system, we can lift, lower, or move heavy loads with less effort than if we were to do so manually. This makes tasks like hoisting items or lifting weights more manageable and efficient.
What is more efficient an inclined plane or a lever?
In terms of energy efficiency, a lever is typically more efficient than an inclined plane because it allows for the same work to be done with less force. Levers utilize the principle of torque, which enables them to magnify the force applied to them. However, the efficiency can depend on the specific task and design of the mechanism.
