What is mechanical advantage?
Factor by which a machine multiplies the effort force
.

How do you find the mechanical advantage of most simple machines?

You multiplies the effort

How can you find the mechanical advantage of levers?
Use effort arm and resistance arm to determine the mechanical advantage of a lever

What is the mechanical advantage of a lever with and effort arm of 16cm and resistance arm of 2cm? 34 cm

A machine has a mechanical advantage of 4. Your effort force is 10 newtons. What is the resistance force? 40 effort

Air is held within a frictionless piston-cylinder container, which is oriented vertically. the mass of the piston is 0.45 kg and the cross-sectional area is 0.0030 m2. initially (state 1) the pressure of the gas is sufficient to support the weight of the piston as well as the force exerted by the atmospheric pressure ( 101.32 kpa). the volume occupied by the air within the cylinder in state 1 is 1.00 liter. one end of a spring (with spring constant k = 1000 n/m) is attached to the top of the piston, while the other end of the spring is attached to a stage that can move vertically. initially the spring is undeflected and therefore exerts no force. then the stage is then moved quasistatically downward a distance of 10.0 cm, at which point the system reaches state 2. the piston-cylinder is not insulated; rather it remains in diathermal contact with the surroundings, which are at a constant temperature of 300 k. what is the change of pressure within the container?

The charge on an electron is 1.60218 × 10−19 c and its mass is 9.10939 × 10−31 kg. how strong a magnetic field must be experienced by the electron if its path is a circle of radius 5.5 cm? answer in units of t.
