Why is the ima always greater than the ama for an inclined plane?
In an inclined plane, the mechanical advantage (MA) is always less than 1 because the input force needed to lift an object is greater than the output force. This is due to the trade-off between the distance over which the force is applied (input distance) and the vertical distance the object is lifted (output distance). The ideal mechanical advantage (IMA) assumes a frictionless system and is calculated based on the ratio of input distance to output distance, resulting in a value always greater than the AMA.
If you exert an input force over a greater distance than the distance exerted by the output force for an ideal machine compare the size of the input and output forces.?
In an ideal machine, if you exert an input force over a greater distance than the output force, the input force will be smaller than the output force. This is because work input is equal to work output in an ideal machine, and work is calculated as force times distance. Therefore, if the input force acts over a greater distance, the output force must be larger to balance the work done.
If you exert an input force over a greater distance than the distance exerted by the output force for an ideal machine compare the size of the input and output forces?
In an ideal machine, the input force will be smaller than the output force when the input force is exerted over a greater distance than the output force. This is because work input and work output must be equal in an ideal machine, and since work = force x distance, a smaller input force over a greater distance will result in a larger output force over a shorter distance to maintain equilibrium.
What is the difference between mechanical advantage and Efficiency?
No relation. Mechanical advantage is a ratio (between the force applied to the mechanism and the external force provided by you ). Efficiency is the fraction of energy actually useful after taking into acount frictional losses etc.
The output force of a rake is greater than the input force?
This is possible when using a lever system with the rake, where the input force is applied over a shorter distance but results in a greater output force over a longer distance. The mechanical advantage gained from the lever system allows for the output force to be greater than the input force in this scenario.
What is a comparison of a machine's work output and work input?
Output is always greater than input. The output is multiplied from input.

What is the formula of each simple machine by getting the work exerted by the machine?
The formula for work exerted by each simple machine is: Lever: Work = Input force × Input distance = Output force × Output distance Inclined plane: Work = Input force × Input distance = Output force × Output distance Pulley: Work = Input force × Input distance = Output force × Output distance Wheel and axle: Work = Input force × Input radius = Output force × Output radius Wedge: Work = Input force × Input distance = Output force × Output distance Screw: Work = Input force × Input distance = Output force × Output distance
Why is the output force always less than the input force in the third class lever?
Because the output distance is always greaterthan the input distance,and the product of (force) x (distance) is nearly the same on both ends.
What is input and output distance?
Input distance is the distance from the input device to the system processing the input, while output distance is the distance from the system processing the output to the output device. These measures are important in various fields such as engineering and technology to ensure efficient and accurate communication between input and output devices.
What type of lever is the output force smaller than the input force?
A second-class lever. In this type of lever, the output force is always smaller than the input force, but the trade-off is that the output force moves a greater distance than the input force. Examples of second-class levers include wheelbarrows and nutcrackers.
If a mechanical advantage of a simple machine is increased how does the distance of the input force compare to the distance of the output force?
If the mechanical advantage of a simple machine is increased, the distance the input force must be applied decreases in relation to the output force. This means that you can exert less input force over a longer distance to achieve a greater output force over a shorter distance.
Suppose work input is 25 J and the output distance is 10 m. Factoring in the effect of friction which must be true about output force?
Considering the work input and output distance, to account for the effect of friction, the output force must be greater than the input force due to the work lost to friction. This means that the output force required to move the object the specified distance against friction will be higher than what would be calculated based solely on the given work input and output distance.
