: A rectangular plate 1.5m wide and 2.5m deep is placed vertically in water so that the center of plate is 4m below the free surface. Determine the total pressure and the depth of center of pressure. State also whether the equilibrium is stable or unstable. The above rectangular plate is taken out of the water which weighs 350.5 N in air and 173.3 N in water of specific gravity 0.99. Find the volume and specific gravity of the plate. Draw a neat sketch

Using Matlab, create a code that determines the highest real root of f(x)=x3-6x2+11x-6.1 using the Newton-Raphson method with x0=3.5 for three iterations. Verify that the process is quadratically convergent.

I found the code to get the highest real root (root for three iterations = 3.0473), however, I do not know how to verify that it is quadratically convergent.

Please select the reinforcement spacing for the entire span of a simply supported beam on a 22 ft span. Use the detailed method to calculate Vc. Do not use a shear envelope diagram use the regular shear force diagram. Use b = 16 in., d = 27 in., the main bending reinforcement consists of 4 #9 bars. The unfactored dead and live loads are 2.6 Kip/ft and 2.5 kip/ft, respectively, f’c = 4500 psi, and fy = 60,000 psi. Use #3 U stirrups. Also, locate in your beam the point beyond which no stirrups are required and find the distance from that point to the supports and to midspan. Use any allowable shear force reduction permitted by the ACI code. Provide a sketch of your final design.

Complete the bending design of a simply supported reinforced concrete beam with the following parameters: Service loads are W_D = 2.5 Kip/ft and W_L = 1.5 Kip/ft, Span = 16 ft, f'c = 6,000 psi, fy = 40,000 psi, b = 12 in., cover to the center of the steel = 3 in. Assume phi = 0.9, but make sure that phi is actually 0.9 at the end. Find h by doubling the recommended minimum height for this beam and provide it in whole inches rounded up to the nearest inch.

Design a rectangular footing for an 18-in square interior column with a dead load of 210 k and a live load of 180 k.

The Mass Moment of Inertia of a body is a property that measures the resistance of the body to angular acceleration

The Parallel-Axis Theorem is I = I_G + md²

The resultant (summation) moment about the mass center due to all the external forces is equal to the moment of inertia about center of mass times the angular velocity of the body.

Mathematically, three equations with four unknowns cannot be solved.

The kinetic energy of a rigid body can be expressed as the sum of its translational and rotational kinetic energies.

To find the kinetic energy of a rigid body with Pure Translation, the rotational kinetic energy is not zero.

Reactions at fixed supports do no work because the displacement at their point of application is zero.
