What would your bathroom scale read if you weighed yourself on an inclined plane? Assume the mechanism functions properly, even at an angle.
Solution 21Q: Reading of the bathroom scale depends upon the angle at which the force is applied. Step 1 of 2 Concept:Newton’s third law: To every action, there is an equal and opposite reaction. Step 2 of 2 Figure below shows the free body diagram of weight of the person W acting vertically downward. If angle of inclination of the plane is , we can resolve it into two components 1) Horizontal component Wsin, acting down the plane 2) Vertical component Wcos, acting perpendicular to the plane
