What is the mechanical advantage of using machines?
Mechanical advantage is the ratio of output force to input force. In other words, F out/F in. Output force is the work done by the machine while input force is what the host (you) did to the machine. Work is always displayed with the label of joules.
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 class or classes of lever always have a mechanical advantage greater than 1?
A second class lever always has a mechanical advantage greater than 1.
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
Mechanical advantage of a 3rd class lever?
always less than 1

Why is the actual mechanical advantage of an inclined plane alwaysess than the theoretical mechanical advantage?
This is because the actual mechanical advantage is the actual calculation found after dividing the effort force by the output force. Ideal mechanical advantage is what many people would call an estimate. When estimating mechanical advantage, the numbers are always rounded. This makes actual mechanical advantage less.

Which type of lever always increases mechanical advantage?
second class lever
Mechanical advantage of a 3rd class lever?
always less than 1
The mechanical advantage of a second class lever?
... is always less than 1 .
What is the mechanical advantage of a machine that changes only the direction of applied force?
if only the direction changes,the input force will be the same as the output force.the mechanical advantage will always be 1.
What is the mechanical advantage is a machine that changes only the direction of the applied force?
if only the direction changes,the input force will be the same as the output force.the mechanical advantage will always be 1.
Why inclined planes are classified as force multipliers?
Because it always has a mechanical advantage greater then 1.
Can the actual mechanical advantage of a machine ever be greater then its ideal mechanical advantage?
In real machines, there is always friction that reduces the efficiency of the machine.This reduces the mechanical advantage because some of the input force has to be used to overcome the force of friction in the machine.To reduce friction in the machine, you could add a lubricant such as oil.
