Questions & Step-by-Step Solutions

A torque of 12 Nm is applied to a lever arm of 0.4 m. What is the force applied?
  • Step 1: Understand the formula for torque, which is Torque = Force x Distance.
  • Step 2: Rearrange the formula to find Force: Force = Torque / Distance.
  • Step 3: Identify the values given in the question: Torque = 12 Nm and Distance = 0.4 m.
  • Step 4: Substitute the values into the formula: Force = 12 Nm / 0.4 m.
  • Step 5: Calculate the result: 12 divided by 0.4 equals 30.
  • Step 6: Conclude that the force applied is 30 N.
  • Torque Calculation – Understanding the relationship between torque, force, and distance using the formula Torque = Force x Distance.
