With reference to the data given in Problem1, a contractoris assigned to work on an extension to the sea pier. The contractor finds that theprofits Y of the job are directly decreased by the number of days per month Xof high-amplitude waves acting on the sea front. It is estimated that Y = 10,000(10 – X).Determine the pmf of Y and the mean and variance of Y.Problem. 3:Contract analysis.

L00 2 One procedure for defining a system viscous damping matrix C that leads to a diagonal generalized damping matrix C is to employ Rayleigh damping, which is defined by C = a,M + a;K (10.76) This is also called proportional damping, since the damping matrix is proportional to a linear combination of the mass matrix and the stiffness matrix. The constants a, and a, can be chosen to produce specified modal damping factors for two selected modes. Combining Eqs. 10.74, 10.75, and 10.76, we get (a) Determine the Rayleigh damping coefficients ao and a, in Eq. 10.76 such that the 3-DOF system has damping facrors š, = 52 = 0.01 in its first two modes.
