That question belongs to a vinyl record player. It is the distance from the pivot of the tone arm to the cartridge with the replay needle.
An arm's length is a distance approximately equal to the length of a human arm, sometimes used figuratively.
Divide the length of the force arm by the length of the resistance arm.
Ideal Mechanical Advantage
The length of one arm is about 40% of your height
there is a correlation in the ratio between the arm length and the leg length. the ratio is 1.556 inches.
The average arm length of an adult is approximately 25-30 inches (64-76 cm) from the shoulder to the fingertips. Arm length can vary based on factors such as height, gender, and genetics.
Mechanical advantage= effort arm length/ load arm length For Example Effort arm=120 cm Load arm length= 40 cm MA-120/40 = 3
To tone the skin means to make all your skin the same color. Like some peoples' arm may be white at the top but then the rest is tan. So some people may want to tone their arm skin to make their whole arm the same color.
The ratio of the human thumb to the length of the arm is usually 1 to 15. The thumb's length can fit into the size of the arm an approximately 15 times or more.
The 'ideal' mechanical advantage is length of the effort arm/length of the load arm .
It means, literally, the length of your arm. Not so literally, it means keeping something or someone at a distance.
Typically foreclosures are not considered to be "Arm's Length" as one of the parties is acting under duress.
