Hi, can you help me with this question? With my friend's help, I somehow got the answer, but I still don't understand how to get to this answer.
Hi, thank you for your question.
I think an important step to approach these types of questions is to draw a diagram. (Like the following)
After you identified the force, distance (from the pivot), and angle (between force and the arm), it's a simple torque question.
Does this answer your question?
