Question

A force of 50 lbs is applied to a 1-foot diameter wheel. the wheel is turning
a.25" diameter axle. how much mechanical advantage does the wheel provide?

Answer 1

To solve this problem you must apply the proccedure shown below:
 1. You must apply the formula for calculate the mechanical advantage, which is:
 M.A=Wheel radius/Axle radius
 2. Therefore, you have:
 Axle radius=0.25 inches=0.0208 feet
 Wheel radius=1 feet
 M.A=1 feet/0.0208 feet
 M.A=48
 Therefore, the answer is: 48

Answer 2

Answer:

Mechanical Advantage=48

Explanation:

A force of 50 lbs is applied to a 1-foot diameter wheel. the wheel is turning

a.25" diameter axle. how much mechanical advantage does the wheel provide?

this is a perfect example of a machine. A machine is a device which enables work to be done in a quick and convenient way.

mechanical advantage of a machine ma is the ratio of load to the effort

MA = radius of wheel/radius of axle

1 foot makes 12 inches

radius=diameter/2

radius of the wheel is 6 inches

radius of axle=.25/2

0.125 inches

MA=6 inches/0.125 inches

Mechanical Advantage=48
