You are the network administrator of a branch office of your company. the branch office network is part of a wan that covers most of the united states. the office has two windows 2000 servers, two unix servers, one windows nt server, 90 windows 98 clients, 40 windows 2000 professional clients, and five macintosh clients. users have been complaining that they are unable to access resources over the wan at the main headquarters. you suspect that one of the routers between your office and the main headquarters is not working properly. what tcp/ip utility can you use to see if a router is not working properly?

5.a fishing rod is formed from a composite material of 0.5 kg of glass fibers embedded in a matrix of 0.5 kg of epoxy resin. the glass fibers are assumed to be long, continuous and unidirectional. to achieve a greater stiffness it is proposed to use a different composite that is comprised of long continuous carbon fibers that will be embedded in a matrix of 0.5 kg of epoxy resin. if the modulus of elasticity of the carbon fiber composite is 10% greater than the elastic modulus of the glass fiber composite, estimate the mass of carbon fibers that will be used to make the carbon fiber composite. assume the applied tensile stress is parallel to the direction of the long axis of the fibers. the epoxy resin, glass fiber, and carbon fiber have an elastic modulus of 5, 86, and 350 gpa respectively and a density of 1100, 2500, and 1800 respectively.
