The state of plane stress at a point on a body can be depicted by the mohr's circle below. point x has coordinates (−10,−21) mpa and point y has coordinates (25,21) mpa.
determine the normal and shear stresses associated with a rotation of the stress element θ=28°. remember that a negative sign indicates a clockwise rotation and a positive sign indicates a counter-clockwise rotation. note that you can use the mohr's circle to obtain your answers graphically or you can apply the stress transformation equations.
determine the σx′, σy′ , and τx′y′

An array of m-50 thermoelectric modules is installed on the exhaust of a sports car. each module has an effective seebeck coefficient of sp of 0.143 5vk and an internal electrical resistance of r.-4 ? in addition, : (15 points each module is of width w 60mm and contains n=100 pairs of semiconducting pellets. each pellet hasan overall length of 2l-5mm and a cross-sectional area as 1.2 x 10'm and is characterized by a thermal conductivity of kpl2w rnk. the hot side of each module is exposed to exhaust gases at·p650c with hia4ow rrk while the osite side of each module is cooled by pressurized water at surface) and 156 °c (at the cool surface). 11s c with h: -500w/m'k. the modules are wired n series and the load resistance is r d=400ohm .the module surface temperatures, t, and ts are 183 "c (at the hot surface and 156c (at the cool surface) a)-draw a schematic of this scenario and label all parts. a. b. if the induced current, i, is 0.15 amps, what is the total power (pa) for one module? c. what is the total power harvest from the exhaust with all 50 modules?
