Q
Q: A door is pushed at its edge with a force of 20 N. If the width of the door is 1 m, what is the torque about the hinges?
Solution:
Torque (τ) = F × d = 20 N × 1 m = 20 Nm.
Steps: 5
Show Steps
Step 1: Identify the force applied to the door. In this case, the force is 20 N.
Step 2: Identify the distance from the hinges to the point where the force is applied. The width of the door is 1 m.
Step 3: Use the formula for torque, which is Torque (τ) = Force (F) × Distance (d).
Step 4: Substitute the values into the formula: τ = 20 N × 1 m.
Step 5: Calculate the torque: τ = 20 Nm.
