Question

If an input force of 202 N is applied to the handles of the wheelbarrow with a mechanical advantage of 2.2. How large is the output force that just lifts the load

Answer 1

For this case, the relationship between the two forces is given by:

`F1 = nF2`

Where,

• F1: output strength
• F2: input force
• n: mechanical advantage

Then, replacing the values ​​we have:

`F1 = (2.2) (202)`

Having the calculations we have:

`F1 = 444.4 N`

Answer:

the output force that only lifts the load is:

`F1 = 444.4 N`
