A 1.25 in by 3 in rectangular steel bar is used as a diagonal tension member in a bridge trust. The Diagonal member is 20 feet long, and it’s module of elasticity is 30 million psi. If the strain in the digital member is measured as .001200

Give heat transfer applications for the following, (i) gas turbines (propulsion) ) gas turbines (power generation). (iii) steam turbines. (iv) combined heat and power (chp). (v) automotive engines

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

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.
