A simply supported wide-flange beam of span length L carries a vertical concentrated load P acting through the centroid C at the midpoint of the span (see figure). The beam is attached to supports inclined at an angle α to the horizontal.
Determine the orientation of the neutral axis and calculate the maximum stresses at the outside corners of the cross section (points A, B, D, and E) due to the load P. Data for the beam are as follows: W 250 × 44.8 section, L 3.5 m,P = 18 kN, and α = 26.57°. (Note: See Table E-1b of Appendix E for the dimensions and properties of the beam.)
The vapour has 5 K of superheat at entry to the compressor.In each case calculate the C.O.P.(ref.) and the refrigerating effect per kg. What would be the C.O.P.(ref.) of a reversed Carnot cycle operating between the same saturation temperatures?
two 20mm steel plates are welded to a rolled S section as shown. Determine the moments of inertia and the radii of gyration of the combined section with respect to the centroidal x and y axes.
Water in the pictured piston cylinder assembly has an initial quality of 10%. The piston cylinder is 20 cm in width and the piston is initially 40 cm high. Heat is added until the temperature of the steam reaches 500°C. While heat is being added the ..
