This is for 5/6

You have a see-saw. One end of the see saw is tied to the ceiling as shown. It is in equilibrium. There is one fulcrum marked 'A' and two children, Kendall and Lauren. What is the tension in the string7 What, is the vertical force, F, at the fulcrum? You have a massless meter stick. Scale 1 is at 20cm and Scale 2 is at 80cm. Mass ] is 10kg at 0cm. Mass 2 is 8kg at 70cm. What is the force measured on scale 1? What is the force measured at scale 2? Use only torque. Draw the picture

Explanation / Answer

equating torque

200*1.5=180*.5+2.5T

=> T= 84 N
