Yes, two probabilities.
The quotient of two quantities called a ratio.
Any two non-zero quantities are always proportional. If the two quantities are X and Y, they are proportional to X/Y.
What is called a statement of comparing of two or more different quantities
A ratio is a comparison of two quantities
A ratio uses division to compare two quantities.
=, > or <.
Mechanical Advantage;The ratio of load and effort is called mechanical advantage of any machine.Mathematical Formula Of Mechanical AdvantageMechanical Advantage = Load / EffortUnit Of Mechanical AdvantageAs mechanical advantage is the ratio of two forces, therefore it has no unit.
Yes, two probabilities.
Yes
to compare the two quantities
The actual mechanical advantage is the measured force output divided by the measured force input, while the theoretical mechanical advantage is calculated based on the quotient of the load distance and effort distance. Comparing the two allows us to evaluate the efficiency and effectiveness of the machine in translating input force into output force. Discrepancies between the actual and theoretical mechanical advantages signify losses due to factors like friction, inertia, or other inefficiencies in the system.
Two words, mechanical advantage.
A first-class lever always increases mechanical advantage, as the effort arm is longer than the load arm. The mechanical advantage is determined by the ratio of the lengths of the two arms of the lever.
A fixed pulley has a mechanical advantage of 1, meaning it doesn't provide any mechanical advantage, but it changes the direction of the force. A free pulley also has a mechanical advantage of 1, as it only changes the direction of the force without providing any mechanical advantage.
Rate is a comparison based on division.
None. Mechanical advantage is a ratio of two measures each of which has the same units and so it is a unit-less number.
