A 3.60-kg mass hangs vertically downward from a massless spring of spring constant 141.0 N/m. What is the length that the spring stretches from its equilibrium position when the mass is hung from the spring? Tries 0/10 The system is set into a simple harmonic motion by pulling the mass down 0.0551 m and releasing it. What is the frequency of the motion? Tries 0/10 What is the amplitude of the oscillation?

E9-13 Computing Four Present Value Problems LO9-7 On January 1 of this year, Shannon Company completed the following transactions (assume a 8% annual interest rate): (FV of $1, PV of $1, FVA of $1, and PVA of $1) (Use the appropriate factor(s) from the tables provided) a. Bought a delivery truck and agreed to pay $60,500 at the end of three years. b. Rented an office building and was given the option of paying $10,500 at the end of each of the next three years or paying $28,500 immediately. c. Established a savings account by depositing a single amount that will increase to $91,000 at the end of seven years. d. Decided to deposit a single sum in the bank that will provide 8 equal annual year-end payments of $40,500 to a retired employee (payments starting December 31 of this year). Required: 1. What is the cost of the truck that should be recorded at the time of purchase? (Round your answer to nearest whole dollar) 2. Which option for the office building results in the lowest present value? Pay in single installment Pay in three installments 3. What single amount must be deposited in this account on January 1 of this year? (Round your answer to nearest whole dollar.) 4. What single sum must be deposited in the bank on January 1 of this year? (Round your answer to nearest whole dollar.)

1. A displacement field is given in terms of scalar components by: $u_1 = a_1x_2^2$, $u_2 = a_2$, $u_3 = a_3x_2x_3$, where $a_1, a_2, a_3$ are positive constants. a) Find the infinitesimal strain tensor. b) Find the longitudinal strain in the direction $\vec{v} = (\hat{e}_1 + \hat{e}_3)/\sqrt{2}$ and the shear strain between $\vec{v'} = (\hat{e}_1 + \hat{e}_3)/\sqrt{2}$ and $\vec{v''} = \hat{e}_2$ at a point whose position is given by the Cartesian coordinates: $x_1 = 1/2, x_2 = 1/2, x_3 = 1/2$. c) Determine the principal strain and the principal directions of strain for the same point as in part b), with $a_1 = 0.05, a_3 = 0.01$. Also determine the maximum orthogonal shear strain.
