Torque and Rotational Equilibrium — Homework
Sketch the pivot and lever arm before writing any torque equation.
- 1.A 40 N force is applied perpendicular to a lever arm 0.25 m from the pivot. Find the torque.
- 2.A seesaw has a 150 N child sitting 3 m from the pivot. Find where a 100 N child must sit to balance it.
- 3.A 60 N force is applied at 30 degrees to a 0.2 m lever arm. Find the torque.
- 4.Explain why a force applied directly at the pivot point (r=0) produces zero torque, no matter how large the force is.
- 5.Describe a real lever or torque example (a door handle, a wrench, a seesaw, a crowbar) and explain why its design takes advantage of a longer lever arm.
