What is the distance of F = {F} N from the pivot point in order for the seesaw to be balanced? Round the answer to 2 decimal places.
A: 11.5/{F} (formula; values not in the backup's text)

Q: The cylinder head was tightened with a wrench. The moment of the wrench was set to 60 Nm. What force must be applied to the handle of the wrench if the distance from the pivot point to the point of application is {r} mm?
A: 60/({r}/1000) (formula; values not in the backup's text)

Q: The maximum lifting moment of the crane is {M} kNm. What is the maximum mass that can be lifted from a distance of 5,0 m?
A: {M}*1000/9.81/5 (formula; values not in the backup's text)

Q: A pike was weighed using a traditional balance. The distance from the pivot point to the weight’s center of mass was {r} m. The mass of the weight was 0,50 kg. How much did the pike weigh when the balance was in equilibrium with the pike at a distance of 0,10 m from the pivot point?

A: 0.5*9.81*{r}/0.1/9.81 (formula; values not in the backup's text)

Q: A nut was tightened with a wrench. The tightening force was {F} N and the distance from the pivot point to the center of the nut was 280 mm. What was the moment?
A: {F}*280/1000 (formula; values not in the backup's text)
