Questions & Step-by-Step Solutions

In a seesaw, if one child exerts a torque of 30 N·m on one side, what torque must the other child exert to balance it?
  • Step 1: Understand what torque is. Torque is a measure of how much a force acting on an object causes that object to rotate.
  • Step 2: Know that in a seesaw, for it to be balanced, the torque on one side must equal the torque on the other side.
  • Step 3: Identify the torque exerted by the first child, which is 30 N·m.
  • Step 4: To balance the seesaw, the second child must exert the same amount of torque, which is also 30 N·m.
