For an experiment, a very sensitive Nano-silver wire has been coated with special material to detect specific material in the air, by measuring electrical properties of the wire. To set up the system and measuring the electrical properties, the scientist is required to send and electrical current through the wire which produces uniform volumetric heat generationil At the steady condition and for a long wire assembly (ie. LD, when T T(r), a) Find the temperature profile inside the wire. b) Locate the location of maximum temperature. c) At constant E 100 [mV],Find the maximum allowable electrical current in [A] to avoid any wire melting. Kril, TAg Allowable = 100[°C] Conductor, k2 Core, k1 4g T = T(r) irI

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
