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 1.93 N · m torque (about the pivot point) in order to pull a weed, determine the resistive force (in N) the weed exerts on the weed puller.

Respuesta :

Answer:

96.5 N

Explanation:

torque = 1.93 Nm

force = torque/distance

10cm = 0.1m

2cm = 0.02m

force = 1.93/0.1

force = 19.3 N

now, mechanical advantage (MA) = (distance from the applied force to the pivot point) divided by (distance from the load point to the pivot point)

MA = 0.1/0.02

MA = 5:1

therefore,

force exerted by weed = 19.3 x 5 = 96.5 N
