Sure! Here’s the transcribed and explained content: --- ### Calculating the Moment of Inertia for a Paraboloid **Problem Statement:** Find - (a) dm - (b) m - (c) write the relation for \( dI_x \) - (d) determine the moment of inertia for mass of the body with respect to the \( x \)-axis of the paraboloid shown, assuming that it has a uniform density and a mass m. --- ### Diagram Explanation: The diagram depicts a three-dimensional paraboloid, which is a solid of revolution generated by rotating a parabola around its axis of symmetry. The key features shown in the diagram are: 1. **Coordinate Axes**: - The axes are labeled \( x \), \( y \), and \( z \). - The paraboloid is oriented along the \( x \)-axis. 2. **Equation**: - The surface equation of the paraboloid is given by \( y^2 + z^2 = kx \), where \( k \) is a constant. 3. **Dimensions**: - The height along the \( x \)-axis is labeled as \( h \). - The radius at the open end of the paraboloid is labeled as \( a \). ### Explanation: To solve the problem: - Determine the differential mass element \( dm \) of the paraboloid. - Calculate the total mass \( m \) of the paraboloid, assuming uniform density. - Write the relation for the differential moment of inertia \( dI_x \). - Determine the moment of inertia about the \( x \)-axis. This problem involves applying principles of calculus and physics to compute the required quantities.
