a lever with an effort arm of 2 inches
A mechanical pencil is just about the same size as a normal pencil, about 6 inches long.
A meter is 100cm where as a yard is 36 inches so its easier

You know the exact measurement of something, wether it is Cenemiters or Inches... You can draw a straight line with the ruler as your guide line... And it's a GREAT object to smack people with!!!
0.03 inches = 3/100 inches.0.03 inches = 3/100 inches.0.03 inches = 3/100 inches.0.03 inches = 3/100 inches.
answer is 4
A lever with a longer effort arm and a shorter resistance arm would have more mechanical advantage. In this case, if you increase the effort arm to 7 inches while keeping the resistance arm at 3 inches, the mechanical advantage would increase. This is because a longer effort arm allows for less force to be applied to overcome a greater resistance.
The mechanical advantage of a first class lever is calculated as the ratio of the effort arm to the resistance arm. In this case, the effort arm is 40 inches and the resistance arm is 10 inches, giving a mechanical advantage of 4:1. This means that the lever can multiply the input force by a factor of 4.
A lever with a resistance arm of 3 inches and an effort arm of 1 inch would have more mechanical advantage as the effort arm is shorter than the resistance arm, making it easier to lift the load.
40/10 = 4
A mechanical pencil is just about the same size as a normal pencil, about 6 inches long.
The mechanical advantage of a ramp can be calculated as the ratio of the length of the ramp to the vertical height it spans. In this case, the mechanical advantage is 50 inches (length of the ramp) divided by 20 inches (vertical height), which equals 2.5. So, the mechanical advantage of this ramp is 2.5.
72 inches by 42 inches. 72 inches by 48 inches. For outdoor use backboard surface area is reduced and the top and base is contoured to reduce wind resistance.
