Q
Q: A torque of 12 Nm is applied to a wheel with a radius of 0.4 m. What is the force applied tangentially to the wheel?
Solution:
Using τ = F × r, we have F = τ / r = 12 Nm / 0.4 m = 30 N.
Steps: 6
Show Steps
Step 1: Understand the formula for torque (τ), which is τ = F × r, where F is the force and r is the radius.
Step 2: Identify the values given in the question: torque (τ) is 12 Nm and radius (r) is 0.4 m.
Step 3: Rearrange the formula to solve for force (F): F = τ / r.
Step 4: Substitute the values into the formula: F = 12 Nm / 0.4 m.
Step 5: Calculate the force: 12 divided by 0.4 equals 30.
Step 6: Conclude that the force applied tangentially to the wheel is 30 N.
