The wheel and axle is helpful because it reduces the effort needed to move a load. What is the trade off for this advantage?
Mechanical advantage
What else can I help you with?
What happens to the mechanical advantage as you move the effort force closer to the fulcrum?
As you move the effort force closer to the fulcrum, the mechanical advantage decreases. This is because the input force is applied over a shorter lever arm, which reduces the moment arms on both sides of the fulcrum, resulting in a smaller mechanical advantage.
The advantage of using an inclined plane to lift an object is that it reduces the?
Force required to move the object forward.
An inclined plane reduces the effort by?
Lesser the height of inclined plane, and more the length of it, More will be the mechanical advantage of inclined plane i.e less effort would be applied.
What is the advantage of using an inclined plane to lift an object is that it reduces the amount of?
The advantage of using an inclined plane to lift an object is that it reduces the amount of force needed to lift the object. By increasing the distance over which the force is applied, an inclined plane decreases the amount of effort required to lift an object to a certain height.
If a wheel and axle has a mechanical advantage of 3 what effort force is required to move a load of 30 N?
The effort force required would be 10 N. This is because mechanical advantage is calculated as Load force/Effort force, so the Effort force = Load force/Mechanical advantage. In this case, 30 N (Load force) divided by 3 (Mechanical advantage) equals 10 N for the Effort force.
If you grease a ramp to make a box slide more easily the ramp and mechanical advantage increases because has been reduced.?
Greasing a ramp reduces friction between the ramp and the box, making it easier for the box to slide. This reduction in friction increases the mechanical advantage of the system, allowing the box to move with less effort.
What is the formula of calculating effort distance in mechanical advantage?
The formula to calculate effort distance in mechanical advantage is Effort Distance = Load Distance / Mechanical Advantage. This means that effort distance is the distance over which the effort force is applied to move the load in a machine.
Advantage of 2nd class lever?
The 2nd class lever reduces the mass of an object, thus it reduces the amount of effort required to lift it. Eg: A wheelbarrow is a 2nd class lever, you are able to move a heavy object with it that you otherwise wouldn't be able to move by yourself.
How do you calculate the mechanical advantage of a moveable pukkey?
To calculate the mechanical advantage of a movable pulley system, you divide the load force by the effort force. The formula is MA = Load Force / Effort Force. The mechanical advantage of a movable pulley is always 2 because the effort force is half the load force when using a system with a movable pulley.
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.
How can you find effort force?
Effort force can be found by dividing the load force by the mechanical advantage of the system. The mechanical advantage is the ratio of the load force to the effort force in a simple machine. Alternatively, effort force can be calculated using the formula Effort Force = Load Force / Mechanical Advantage.
Why the value of single movable pulley is 2?
A single movable pulley has a mechanical advantage of 2 because it reduces the effort needed to lift an object by half. This is due to the pulley system allowing the weight to be distributed between the weight being lifted and the tension in the supporting rope.
