- Q1 A three-level offshore platform located in the Helang Oilfield area has a 1500 kg floor steel grating supported at each level. The structure sometimes is subjected to a vertical ocillation movement during rough sea waves given by function of y(t) = Y sin ot If the steel grating only moves in the vertical direction and is supported by one equivalent spring and damper at each steel grating pole level with stiffness, k, = (300 xT) Nim, k= (200 x T) Nm and k = (100 × T) Ním while damping, c: = (15 x U) Nsm, c: = (10 x U) Ns'm and c; = (5 x U) Nsim, respectively, as simplified in Figure Q1.

Identify the correct description for the formula f'(t)h-¹(f(t+h) − f(t − h)) from the following options: FFD1: forward finite difference with stepsize h for the first derivative of f at t BFD1: backward finite difference with stepsize h for the first derivative of f at t CFD1: central finite difference with stepsize h for the first derivative of f at t CFD2: central finite difference with stepsize h for the second derivative of f at t None of the Above Make your selection here: Selectarrow_forward3. If the temperature of a certain amount of gas is held constant, the absolute pressure of gas varies inversely as its volume without change of state, and if for certain amount of gas, the absolute pressure is 20 psi (pound per square inch) when the volume is 40 liters, then find the volume when the absolute pressure reached 32 psi. 4. The electrical resistance of a wire varies directly as the length and inversely as square of radius. The resistance of a certain piece of wire of length 100 feet and radius 0.02 inch is 300 ohms. Find the resistance of the wire of the same material 2500 feet long and radius 0.05 inch.arrow_forwardIn the Figure 2, the resultant R can be found as: R* Figure 2: R P.
