a tyrannosaurus rex could be up to 46 feet long and weight 10 tons at the most and in height it could reach up to 21 feet high
1.5 feet
it is called a "sleeve" its to keep sweat off your shooting arm
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.
It has a lot to do with the age of the player in relation to the length of the arm. An adult, with an arm 26" or longer would use a full size bow of 29.25". A 6/7 year old with an arm length of about 20" would use a bow length 24.5" Between this age and the adult age, a 27" length is usual. Under normal circumstances, a 15" viola would need a full size bow
Ideal Mechanical Advantage
The length of one arm is about 40% of your height
Full grown octopi vary greatly in size, depending on the species. Some are small enough to fit into your hand and others, like the giant Pacific octopus, can grow to weigh more than 500 pounds.
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
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 .
