What does the mechanical advantage tell us about a machine's usefulness?
The mechanical advantage of a machine tells us how much it can multiply or change the input force. A higher mechanical advantage means the machine is more effective at reducing the force needed to perform a task. Machines with a higher mechanical advantage are generally considered more useful because they make work easier to accomplish.
What is mechanican advantage?
Mechanical advantage is the ratio of output force to input force in a mechanical system. It allows us to determine how much a machine can amplify or multiply the force applied to it. A higher mechanical advantage means that less force is needed to accomplish a task, making work easier.
How is the mechanical advantage determined for a screw?
The mechanical advantage of a screw is determined by comparing the distance traveled along the screw's threads to the force applied to turn the screw. It is calculated as the ratio of the circumference of the screw to the pitch of the screw thread. A higher mechanical advantage indicates that less force is needed to lift a load.
Which lever has the largest mechanical advantage?
the one with the fulcrum closer to the weight you needed to lift
Does a machine's mechanical advantage reduce or increase effort?
A machine's mechanical advantage increases the force output compared to the input force required. This means that the machine helps to reduce the amount of effort needed to perform a task.
The wheel and axle is helpful because it reduces the effort needed to move a load. What is the trade off for this advantage?

Is the mechanical advantage of a compound machine is related to the mechanical advantage of all the simple machines involved?
Yes, the mechanical advantage of a compound machine is directly related to the mechanical advantages of the simple machines that comprise it. The overall mechanical advantage can be calculated by multiplying the mechanical advantages of each individual simple machine within the compound machine. This relationship highlights how the combined effect of multiple simple machines can enhance efficiency and reduce the effort needed to perform work.

Using a pulley system with a mechanical advantage of 10 how large an input force would be needed to lift a stone slab weighing 2500 N?
To calculate the input force needed to lift a stone slab weighing 2500 N with a mechanical advantage of 10, you would divide the weight of the slab by the mechanical advantage. So, the input force required would be 250 N (2500 N / 10).
Can't a simple inclined plane have a mechanical advantage less than one?
No, a simple inclined plane always has a mechanical advantage of greater than or equal to 1. It reduces the force needed to lift an object by increasing the distance over which the force is applied. The mechanical advantage is calculated by dividing the length of the inclined plane by the height.
How many pulley needed to lift a load?
The number of pulleys needed to lift a load varies based on the size of the load. A very small load can be lifted with just one pulley while large loads may require many pulleys to adequately lift the load.
How do pulleys give you a mechanical advantage?
Pulleys provide a mechanical advantage by reducing the amount of force needed to lift a load. This is achieved by distributing the load’s weight across multiple ropes and pulleys, which allows the force required to be divided amongst them. As a result, the effort needed to lift the load is decreased, making the task easier.
Calculate the mechanical advantage of a lever where 5 N of input force is needed to move a 10 N box using that lever.?
The mechanical advantage of the lever is calculated by dividing the output force by the input force. In this case, the output force is 10 N and the input force is 5 N, so the mechanical advantage would be 10 N / 5 N = 2. This means that the lever provides a mechanical advantage of 2, making it easier to lift the box.
