Questions & Step-by-Step Solutions
A door is pushed at its edge with a force of 50 N. If the width of the door is 1.2 m, what is the torque about the hinges?
Step 1: Identify the force applied to the door. In this case, the force is 50 N.
Step 2: Identify the distance from the hinges to the point where the force is applied. The width of the door is 1.2 m.
Step 3: Use the formula for torque, which is Torque = Force × Distance.
Step 4: Substitute the values into the formula: Torque = 50 N × 1.2 m.
Step 5: Calculate the result: 50 N × 1.2 m = 60 Nm.
Step 6: The torque about the hinges is 60 Nm.
Torque – Torque is the measure of the rotational force applied at a distance from a pivot point, calculated as the product of the force and the perpendicular distance from the pivot.
Force and Distance Relationship – Understanding how force applied at a distance from a pivot creates rotational motion, and how to calculate torque using these values.
