A tension member constructed of an L 4 × 4 × 1/2 inch angle section (see Table E-4(a) in Appendix E) is subjected to a tensile load P = 12.5 kips that acts through the point where the midlines of the legs intersect [see figure part (a)].
(a) Determine the maximum tensile stress #t in the angle section.
(b) Recompute the maximum tensile stress if two angels are used and P is applied as shown in the figure part (b).
Air enters a non-ideal gas turbine at T1 = 2290°F, P1 = 196 psia and exits at T2 = 1200°F, P2 = 14 psia. (a) Assuming constant specific heats evaluated at 1000F, find the turbine efficiency using the Air Tables.
Oil (specific gravity, 0.8) flows through a constant-diameter pipe-(pipe diameter, D=3 inches) that goes through a bend of angle, θ=45° The flow rate in the pipe is 0.12 ft3 /s. The pressure in the pipe atAandBis the same, namely, 11 psi . T..
Select a suitable belt and, ignoring the elongation at fitting but using the guide mass/unit length, calculate the power transmitted if the maximum permissible tension is 1kN and the coefficient of friction is 0.25 if the motor rotates at 1450rpm
