LEVERS ACTIVITIES :

1. We have to lift 30kg of rubble with a wheelbarrow. The distance between the debris and the wheel is 25cm and the strength that I do is half of what they weigh the rubble. How far will my hand from the rubble?

Solution: Formula F × f = R * R
15 · x = 25.30
15 · x = 750 x = 750/15

x = 50cm




2. Two boys are playing on the swing in the park. The distance between the two sides of the swing and the center is half a meter (50 cm) one child weighs 25kg. How weigh the other child to lift?

Solution: Formula F × f = R * R
25.50 = x • 50
1250 = x • 50
1250/50 = x
25 = x

If weighing 25kg equates it with weighing 25 eat something and raise it.



3. I have a lever that is 13cm in distance between the fulcrum and the resistance. If the resistance weighs 10kg and the strength that I do is of 2Kg, how far is the strength that I do and the fulcrum?


Solution: Formula F × f = R * R
2 • x = 10.13
2 •
x = 130 x = 130 / 2 x = 65




4. I cut a paper by a force of 5kg. If the distance between the fulcrum and the resistance is 5 cm and between the fulcrum and the force is 2 cm, what is the resistance have to do the folio?


Solution: Formula F × f = R * R
x 5.2 = 5 •
10 / 5 = 5 ° x 2 = x



5. I want to get a nail opposing resistance 2kg and I do a force of 6kg. If the distance between the fulcrum and the force is 4cm how much is the distance between the point of support and resistance?

Solution: Formula F × f = R * R
2.6 = 3 ° x 18 = 3.x

18 / 3 = x

6 = x
