A rod with cross-sectional area of 100mm2 is stretched between two fixed points such that the initial tensile load is 10kN. The rod has a modulus of elasticity equal to 180 GPa and a coefficient of linear expansion of 0.00001m/m-C. The initial tension is designed such that the rod will have zero stress when there is a certain change n temperature of the rod environment. What is the temperature (in C, 2 decimal places)?

A rod with cross-sectional area of 1002 is stretched between two fixed points such that the initial tensile load is 10kN. The road has a modulus of elasticity equal to 180GPa and a coefficient of linear expansion of 0.00001m/m-°C. The initial tension is designated such that the rod will have a zero stress when there is a certain change in temperature of the rod environment. What is the temperature (in °C, 2 decimal places)?

Element (1) is steel with E1 30 x 103ksi, cross - sectional area Ai - 2.0 in, length L1-80 in and coefficient of thermal expansion α1=7x10-6/0F; the corresponding values for the aluminum element (2) are: E2 10 x 103ksi, A2-3.6 in, L,- 60 in, a2 13 x 10-6/oF; the corresponding values for the bronze...
A rigid beam BCD is supported on a roller support at C (4m from B) and has two bars AB and DE attached at each end
A rigid beam BCD is supported on a roller support at C (4m from B) and has two bars AB and DE attached at each end. The bars can carry either tension or compressive forces. The rigid beam carries a UDL of I kN/m across BC and a point load of P at D as shown in the figure above. The length of the two bars is 3000 mm. The elastic modulus of both bars is 200 GPa and the...

2) IP and MAC addressing. True or False. One point for each correct answer, zero points for each incorrect answer. Many of the questions refer to the following network consisting of three 10Mbps Ethernet segments, one switch, and one router. Assume all ARP tables are up-to-date unless otherwise stated. a) Consider a network consisting of Ethernets, hubs, switches, and routers. Suppose one of the hubs is replaced with a switch. Then the network administrator must redefine some IP addresses. True...
