Can Mechanical Advantage be greater than Velocity Ratio for any machine?

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

∙ 11y agoTo clarify: for example, if the mechanical advantage is 2 (output force is twice the input force), the speed ratio of an ideal machine is also 2 (input speed is twice the output speed). The speed ratio can also be greater than 2, in the sense that more input speed is required; this will happen if there is friction, for example. It can not be less, since this would violate Conservation of Energy.

What is the relationship between ideal mechanical advantage and velocity ratio?
The ratio of Mechanical Advantage and Velocity Ratio is Efficiency. That is to say the ratio of M.A. and V.R. is constant.
What is a lever with a mechanical advantage greater than one used to do?
Mechanical advantage refers to the ratio of the force produced by a machine to the force applied to it. A lever with a mechanical advantage greater than one is used to increase distance.
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 do you calculate effort the machine of velocity ratio 5 and efficiency 60 percent calculate the effort required to lift a load of 300N?
efficiency=mechanical advantage/velocity ratio mechanical advantage=load/effort use this formula, ans:100N
What does the output force divided by the input force equal?
Efficiency of a machine or mechanical advantage

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.
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.
How do you calculate effort the machine of velocity ratio 5 and efficiency 60 percent calculate the effort required to lift a load of 300N?
efficiency=mechanical advantage/velocity ratio mechanical advantage=load/effort use this formula, ans:100N
A lever with a mechanical advantage greater than one is used to do what?
A lever with a mechanical advantage greater than one is used to increase distance. A lever is a simple machine connected to ground by a hinge called a fulcrum.
The mechanical advantage of a machine without friciton is called the machine's mechanical advantage?

When is the mechanical advantage greater than one?
The IMA of a machine is greater than 1 whenever the output force is greater than the input force.
Which factor must increase to give a machine a mechanical advantage greater than 1?
output force (:
What is the mechanical advantage of a machine which multiplies distance?
