A hollow circular post ABC supports a load P1 = 1700 lb acting at the top. A second load P2 is uniformly distributed around the cap plate at B. The diameters and thicknesses of the upper and lower parts of the post are dAB= 1.25 in, tAB= 0.5 in, dBC= 2.25 in and tBC= .375 in respectively. A) Calculate the normal stress AB in the upper part of the post. B) If it is desired that the lower part of the post have the same compressive stress as the upper part, what should be the magnitude of the load P2? C) If P1 remains at 1700 lb and P2 is now set at 2260 lb, what new thickness of BC will result in the same compressive stress in both parts?
a cantilevered bean has a lenght of L, a cross section area of A, and a flecural rigidity of EI. The free end is free to rotate and displace due to bending. derive the stiffnes of the cantilevered bean. Assume small deformations.
Water with a static pressure of 1.96kN/M2 flows through an 800 mm diameter pipe. A pitot tube pressure gage in this pipe reads a pressure of 5.88 kN/M2. How do you determine the volume flow rate (Q) of the water? (Q = 1.40 M^3/sec, V=2.79 M/sec)
