Final answer:
The force exerted by the weed on the tool can be calculated using the formula force = torque / distance. However, the distance value is not provided in the question, so the exact force cannot be determined.
Step-by-step explanation:
Torque is the product of force and distance from the pivot point. In this case, the torque required to pull the weed is 1.38 n⋅m. So, to find the force exerted by the weed on the tool, divide the torque by the distance from the pivot point. The formula for torque is:
Torque = Force × Distance
Rearranging the formula:
Force = Torque / Distance
Plugging in the values:
- Torque = 1.38 n⋅m
- Distance = ? (not provided in the question)
Without the distance value, I cannot calculate the exact force exerted by the weed on the tool. Please provide the distance value to get a precise answer.
