What is true about the mechanical advantage of a machine?
it is less than the ideal mechanical advantage
How does actual mechanical advantage compare with ideal mechanical advantage?
The actual mechanical advantage is usually less, due to losses.
What is true about the mechanical advantage of a machine a it increases with greater friction b it decreases as the input distance increases c it is less than the idle mechanical advantage?
c) It is less than the idle mechanical advantage. The actual mechanical advantage of a machine is always less than the ideal mechanical advantage due to factors like friction and energy losses in the system.
What is the mechanical advantage of tweezer?
The mechanical advantage of a pair of tweezers is typically around 1.5 to 2. This means that it requires 1.5 to 2 times less force to pick up an object using the tweezers compared to using just your fingers.
If the output force is less than the input force of a simple machine the mechanical advantage less than one?
it means the mechanical advantage is greater.
If the input force is less than the input force of a simple machine the mechanical advantage is less than one?
it means the mechanical advantage is greater.
Can a inclined plane have a mechanical advantage of less than 1?
The mechanical advantage of an inclined plane is equal to length divided by height (l/h). Therefore, if the length is less than than the height, the mechanical advantage would be less than one.
Why are third class levers used if their mechanical advantage is less that one?
Mechanical advantage is not the only reason to use levers.
Is there a mechanical advantage in a Flagpole?
Yes, a flagpole can have a mechanical advantage when raising or lowering a flag. This is usually achieved by using a pulley system, which allows a person to exert less force to lift the flag due to the advantage gained by redirecting the force through the pulleys.
How does the ideal compare with the actual mechanical advantage?
The ideal mechanical advantage is based on the geometric relationships of a machine's components and assumes no energy losses, while the actual mechanical advantage accounts for friction, inefficiencies, and other factors that can reduce the output compared to the input force. In reality, the actual mechanical advantage is always less than the ideal mechanical advantage due to these energy losses.
Do all levers have a mechanical advantage?
No, not all levers have a mechanical advantage. The mechanical advantage of a lever depends on the specific positions of the effort, load, and fulcrum. Some levers may have a mechanical advantage of less than 1, resulting in a decrease in force but an increase in distance.
