A circular cross section solid steel shaft 3" in diameter and 4 feet long is fixed at one end and free at the other. As shown in the figure below, the shaft is subjected to an axial tensile load of 50,000 lbs. If the force P = 390 lbs, what is the combined stress at point A and point B. Indicate whether they are compressive o
This question involves maximum bending moment calculation, maximum stress calculation, graph sketches of tensile & compressive stress
dimensions for cross sections that minimize stress with given values and % reduction of maximum stress with new calculated cross sections.

1. A pressure vessel is made of a cylindrical composite part produced by filament winding. Hoop winding is used in which the number of winding layer is 5 and the wall thickness for each layer is 1mm. The diameter of the vessel is 0.5m. The fiber material is known to be S-glass with a tensile strength of 4.5GPa, and the matrix m
A solid shaft 125mm did transmits 600kW at 300 revolutions/minute. It is also subjected to a bending moment of 9kN-m and to an end thrust. If the maximum principal stress is limited to 80MPa, determine the permissible end thrust.
Also, determine the position in which the principal stress acts, and draw a diagram showing the p
A cantilever beam is to be made using a symmetrical I section beam. The cantilever is to carry a load of 40kN at a distance 2.5m from the fixed end. The situation allows for a depth of I-beam to be no greater than 250mm. I-beams of this depth are normally supplied with a flange of thickness 8mm and web thickness of 6mm. Calculat
A steel 'stay' of effective length 5m is fitted in between the walls of a ships refrigerated compartment when the temperature is 18 degrees centigrade.
Assume zero stress in the stay on completion of fitting. when the temperature falls to -10 degrees centigrade, the gap between the walls is reduced by 0.5mm.
Determine the str
