A U-tube manometer filled with water, density 1000 kg/m3 shows a height difference of 25 cm. What is the gauge pressure? If the right branch is tilted to make an angle of 30 with the horizontal, what should the length of the column in the tilted tube be relative to the U-tube?
the traveling crane consists of a 5-m-long beam having a uniform mass per unit length of 20kg/m. The chain hoist and its supported load exert a force of 8 kN on the beam when x=2m. draw the shear and moment diagrams for the beam.
Iron is a polytropic material. At room temperature, it has a BCC crystal structure (alpha-iron or ferrite). Upon heating above 912C, it converts to a FCC crystal structure (-iron or austenite). If heated above 1394?C, it converts to a different BCC s..
