Questions & Step-by-Step Solutions

If the angle between the force and the lever arm is 90 degrees, what is the torque produced by a 15 N force applied at a distance of 2 m?
Correct Answer: 30 Nm
  • Step 1: Identify the formula for torque, which is τ = F × d × sin(θ).
  • Step 2: Determine the values given in the problem: the force (F) is 15 N, the distance (d) is 2 m, and the angle (θ) is 90 degrees.
  • Step 3: Calculate sin(90°). The sine of 90 degrees is 1.
  • Step 4: Substitute the values into the torque formula: τ = 15 N × 2 m × 1.
  • Step 5: Perform the multiplication: 15 N × 2 m = 30 Nm.
  • Step 6: Conclude that the torque produced is 30 Nm.
