Q: A Mercury manometer is attached to a pipe having suction pressure. the right limb is open to the atmosphere while the contact between Mercury and water is in left limb at a distance of 30 cm from the center of the pipe. a) if the difference in the level of Mercury in the two limbs is 20 cm. what will be the pressure in the pipe. b) if the pressure in the pipe is increased to 2900 pascal. what will be the new difference in Mercury level.

Learning Goal: An object's moment of inertia is calculated analytically via integration, which involves dividing the object's area into the elemental strips that are parallel to the axes and then performing the integration of the strip's moment of inertia. In practice, engineers often encounter structural members that have areas composed of the common geometric shapes, such as rectangles, triangles, and circles, whose areas, centroidal locations, and moments of inertia about their centroidal axes are either known or can be calculated easily. Determining the moment of inertia of a composite area with respect to any axis is based on the following definitions: I₂ = fy² dA Iy = √x² dA For a composite area consisting of a finite number of components, the integration is replaced by summation and the general equation simplifies to 771 m A composite area consisting of the rectangle, semicircle, and a triangular cutout is shown (Figure 1). Calculate the moment of inertia of the triangle with…
