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

Mechanical Advantage=48

Step-by-step 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

Answer 2

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
