Questions & Step-by-Step Solutions

What is the torque about a pivot if a force of 8 N is applied perpendicular to a lever arm of 0.75 m?
  • Step 1: Identify the force applied. In this case, the force is 8 N.
  • Step 2: Identify the distance from the pivot to where the force is applied. Here, the distance is 0.75 m.
  • Step 3: Understand that torque is calculated by multiplying the force by the distance from the pivot.
  • Step 4: Use the formula for torque: Torque = Force × Distance.
  • Step 5: Substitute the values into the formula: Torque = 8 N × 0.75 m.
  • Step 6: Calculate the result: 8 N × 0.75 m = 6 Nm.
  • Step 7: Conclude that the torque about the pivot is 6 Nm.
