Questions & Step-by-Step Solutions
A torque of 5 N·m is applied to a wheel with a moment of inertia of 2 kg·m². What is the angular acceleration of the wheel?
Step 1: Understand the formula for angular acceleration, which is α = Torque / Moment of Inertia.
Step 2: Identify the values given in the question: Torque = 5 N·m and Moment of Inertia = 2 kg·m².
Step 3: Substitute the values into the formula: α = 5 N·m / 2 kg·m².
Step 4: Perform the division: 5 divided by 2 equals 2.5.
Step 5: Write the final answer: The angular acceleration α is 2.5 rad/s².
Torque and Angular Acceleration – This question tests the relationship between torque, moment of inertia, and angular acceleration, as described by the formula α = Torque/I.
