Abeam with a weight of 100 n nd a length of 12.0 meters is supported at each end. it is supporting a machine with a weight of 1800 n which is located 5.0 m from the left end of the beam. a.) draw a free body diagram for the beam, clearly labeling lol forces, write down the equations which are obtained from newton’s second law. b.) what is the force of support at the right end? c.) what is the force of support at the left end?

Asteel tube (k=50 w/mk) of inner and outer diameter di = 20mm and do=26mm, respectively, is used to transfer heat from hot gases flowing over the tube (h-hot = 200w/m2k) to cold water flowing through the tube (h-cold = 8000 w/m2k). what is the cold-side overall heat transfer coefficient uc? to enhance heat transfer 16 straight fins of rectangular profile are installed longitudinally along the outer surface of the tube. the fins are equally spaced around the circumference of the tube, each having a thickness of 2mm and a length of 15mm. what is the corresponding overall heat transfer coefficient uc? *solve for uc in both cases*
