Question 1 An end capped cylindrical pressure vessel with internal pressure p = fully supported at one end, is also subjected to a force F= 10 kN in the y direction at the other end as shown. The internal diameter of the pressure vessel is d= 160 mm and its thickness is t= 10 mm 3 MPa, assumed to be Determine the magnitudes of the stress components in x, y and z coordinates at points H and K and sketch...
Question 1 Shaft AB is supported at B by a roller support and at A by a pin support as well as a spline that prevents rotation around x axis. The diameter of the shaft is D. At cross section A-A there is a relief groove where the minimum diameter is d. Two loads, F, and one torsion moment, T, are acted on the shaft. The material of the shaft is aluminum 7075, Sy = 495 MPa. Also known: L=630...

A 50 lb motor is bolted to the middle of a 72-inch long plank, and x is the displacement of the motor from its equilibrium position. The plank may be modeled as a simply supported beam with EI 18 x 10 lb-in2. Use the inch-pound-second system of units to work this problem, and use g 386 in/sec2 a) Neglect the mass of the plank and find the system's undamped natural frequency of vibration (ansuwer: f 21.3 Hz) b) Suppose the...

L/2 L/4 L/2 L/4 P/2 P/2 3 pt. Loading 4 pt. Loading 1. The schematics above show two common mechanical testing geometries - a 3 point loaded specimen and 4 point loaded specimen. The samples you would test in these geometries would be called "flexure" samples. P is the load measured by the load cell Samples would actually be longer than L but the contact points determine the loading profile...
