Sure, take your forearm, for instance. It is a lever that trades force for speed because the insertion points for the muscles on the bone (effort) are closer to the fulcrum (elbow) than the resistance (your hand). Your muscle contracts a short distance but that is translated to a greater distance at the hand.
A short effort arm and a longer resistance arm gives a lever with a MA < 1

What is the relationship between ideal mechanical advantage and velocity ratio?
The ideal mechanical advantage is the ratio of the input force to the output force in a system, while the velocity ratio is the ratio of the velocity of the input force to the velocity of the output force. The relationship between them depends on the type of machine, but in general, a higher ideal mechanical advantage tends to be associated with a lower velocity ratio, and vice versa.
The mechanical advantage of a machine is always greater than 1?
well the advantage of that is pie, not math pie but pie that you eat
How many time a force multiplied by a machine is the mechanical?
Mechanical Advantage
What type of machine advantage describes the ability of a machine to increase output force?
mechanical advantage
What is the ratio of output force to input force of a machine?
That's the machine's "mechanical advantage".
What is the relationship between ideal mechanical advantage and velocity ratio?

What is the ratio of output force to input force of a machine?
That's the machine's "mechanical advantage".
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.
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.
How many times a force is multiplied by a machine is the mechanical what?
The number of times a force is multiplied by a machine is known as mechanical advantage. It is calculated by dividing the output force of the machine by the input force applied to it. A mechanical advantage greater than 1 indicates that the machine multiplies the input force.
How does the mechanical advantage of a machine affect it's work output?
The mechanical advantage of a machine indicates how much it multiplies force or velocity. A higher mechanical advantage means the machine requires less input force to achieve a certain output force, but it may trade-off by requiring more input distance. Ultimately, the work output of a machine is affected by its mechanical advantage as it determines the efficiency in transforming input work into output work.
True or False Finding the ratio of input force to output force gives you the mechanical advantage of a machine?
True. The mechanical advantage of a machine is determined by the ratio of output force to input force. A mechanical advantage greater than 1 indicates that the machine amplifies force, making it easier to do work.
What does it mean to say that a machine has a certain mechanical advantage?
When a machine has a certain mechanical advantage, it means that it can multiply the input force applied to it. Mechanical advantage is calculated as the output force divided by the input force required to lift a load. Machines with a mechanical advantage greater than 1 make it easier to lift heavy objects.
