2. My Notes -1 points OSCOLPHYS2016 9.2.WA.005. A gardener is using a tool as shown in the figure to pull weeds. 24 cm You will notice that the tool is designed with a built-in pivot point about which the torques are applied. If the gardener applies a 1.39 Nm torque (about the pivot point) in order to pull a weed, determine the resistive force in N) the weed exerts on the weed puller.

If the children are separated by a distance of 4 m, at what distance from the pivot point is the small child sitting in order to maintain the balance? Additional Materials Reading

Answer 1

- Ø given Torque T = 1.39 N-m Tosquel P = oF 8 = Perpendicular distance Fe applied forces W = [24cm) (F) 1.39 = (0.24) F Force - 1 F = 5.79 NK Answer) mi=18kg p m₂ = 32 kg a from Pivot her small child is at distance Moment of 18kg = moment of 32 kg (18)(x) = (4)(32) [a= Folm.
