How to increase the thermal officiency of an ideal simple rankino cycle? among these methods, which one is the best and why?

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.

Aload of 10kn is to be suddenly applied to the free end of a vertical rod of length 500 mm, the upper end being rigidly fixed. 190 mechanical science what should the diameter of the rod be if the maximum stress in the rod is not to exceed 100 mpa? the tensile modulus of the rod is 205 gpa.
