Question

a carpenter uses a claw hammer to pull a nail from a board. the nail has a resistance of 1,500N. the carpenter applies force of 150N. what is the mechanical advantage of the hammer?

Answer 1

assuming the nail is pulled out when he applies the force of 150N, how many times bigger is the output force than the input force?

Answer 2

uh, im stuck...

Answer 3

the output force is 1500N. the input force is 150N.
\[MA = \frac{F_{output}}{F_{input}} = \frac{1500N}{150N}\]what does that simplify to?

Answer 4

10N?

Answer 5

N/N cancels the unit, mechanical advantage is a ratio, so it has no units. The hammer takes an input force of 150N and multiplies it by 10, for an output force of 1500N. That's what mechanical advantage does

Answer 6

so the answer is 10?

Answer 7

yup

Answer 8

ooh, ok thank you soo much for the help!!
