- The following is used to model a wave that impacts a concrete wall created by the US Navy speed boat.1. Derive the complete piecewise function of F(t) and F()The concrete wall is 2.8 m long with a cross-section area of 0.05 m2. The force at time equal zero is 200 N. It is also known that the mass is modeled as lumped at the end of 1200 kg and Young’s modulus of 3.6 GPa2. Use *Matlab to simulate and plot the total response of the system at zero initial conditions and t0 = 0.5 sarrow_forwardA fixed beam is subjected to a uniformly-distributed load with an intensity of f = 10 N/mm length of L = 200 mm. Now determine the support reaction forces, internal shear forces and moments, then plot its internal shear force and moment diagram. f[N/m] L 1. Define the paramters, use L and f as the variables y Xarrow_forwardProblem Description:Model the bracket in ANSYS Software by using a solid 8 node plane stress element for following description. Geometry: The thickness of the bracket is 3.125 mmMaterial: Assume the structure is made of steel with modulus of elasticity E=200 GPa.Boundary conditions: The bracket is fixed at its left edge.Loading: The bracket is loaded uniformly along its top surface. The load is 2625 N/meter.(i) Plot deformed shape(ii) Determine the principal stress and the von Mises stress. (Use the stress plots to determine these) You are required to solve the above problem in Ansys APDL and submit the results IMPORTANT: Convert all dimensions and forces into SI unitsarrow_forward

The energy loss on the pipe flow (he) due to friction between the pipe and the fluid is determined using Darcy-Weisbach equation, given as h₁ = f (²) (1/1) where f is the friction factor, L is the length of the pipe, D is the diameter of the pipe, V is the velocity of the flow, and g is the gravitational acceleration. The friction factor may be determined using an empirical equation developed by Nikuradse for flow in smooth pipes, given as 1 =0.869 In (Re√7)-0.8 where Re is the Reynolds number of the flow, determined as VDp R₂ = μl The friction factor equation given is only valid for flows with Reynolds number higher than 4000 (turbulent flow). Guide Questions: Determine the Reynolds number of the flow. Is the Nikuradse equation for friction factor…arrow_forward
