What does it mean when mechanical advantage is greater than 1?

A machine with a mechanical advantage of greater than 1 multiplies the input force.

Why is mechanical advantage always less than 1?

M.A is less than one because the effort arm is always shorter than the load arm.

Can the mechanical advantage of a machine can be less than 1?

Mathematically: Mechanical Advantage is force (or torque) output / force (or torque) input. Numerically it can be any number, <<1 to >>1.

Is higher mechanical advantage better or lower?

A common trait runs through all forms of machinery: mechanical advantage, or the ratio of force output to force input. In the case of the lever, a simple machine that will be discussed in detail below, mechanical advantage is high. Most machines, however, work best when mechanical advantage is maximized.

What does the mechanical advantage tell you?

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The performance of a real system relative to this ideal is expressed in terms of efficiency factors that take into account departures from the ideal.

Why is the mechanical advantage of a class 3 lever less than 1?

The mechanical advantage of a lever of the third order is always less than one because the effort arm is always less than the load arm.

Why is the mechanical advantage of a lever of third order is always less than 1 give one example of this class of lever?

Mechanical advantage of a class 3 lever is always less than 1 because the load arm is always longer than effort arm. This helps by reducing the applied force(effort). So, it is a speed multiplier.

Why mechanical advantage is always less than the velocity ratio?

The mechanical advantage of an actual machine is always less than the velocity ratio as there is a loss of energy due to friction.

Which class lever always has a mechanical advantage of less than 1?

Class III levers
Class III levers have mechanical advantage less than one.

Why is no machine 100\% efficient?

A machine cannot be 100 percent efficient because output of a machine is always less than input. A certain amount of work done on a machine is lost to overcome friction and to lift some moving parts of the machine.
