Aplane wall of length l, constant thermal conductivity k and no thermal energy generation undergoes one-dimensional, steady-state conduction. the left hand side surface of the wall is subjected to a constant heat flux q the right hand side surface has a uniform temperature of t,. using the standard approach, find the temperature distribution, the heat flux and rate of heat transfer.

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
