Q
Q: If two equal and opposite forces are applied at the ends of a lever arm of length 1 m, what is the net torque about the center?
Solution:
The net torque is zero because the forces are equal and opposite, producing no rotational effect.
Steps: 5
Show Steps
Step 1: Understand what torque is. Torque is a measure of how much a force acting on an object causes that object to rotate.
Step 2: Identify the lever arm. In this case, the lever arm is 1 meter long.
Step 3: Recognize that there are two forces applied at the ends of the lever arm. These forces are equal in size but opposite in direction.
Step 4: Determine the effect of the forces. Since the forces are equal and opposite, they cancel each other out.
Step 5: Calculate the net torque. Because the forces cancel each other, the net torque about the center of the lever arm is zero.
