Calculate the AMA of an access ramp if it takes 255 N of force to push a person in a wheelchair having a combined weight of 764 N up the incline.

a)2.50
b)2.95
c)3.00
d)1,020

Respuesta :

Actual Mechanical Advantage(AMA) = Weight / Force
Here, Weight = 764 N
Force = 255 N

Substitute the values in to the expression, 
AMA = 764 / 255
AMA = 2.99

After rounding-off to the nearest tenth value, it would be 3

Finally, option C would be your answer.

Hope this helps!
