Chapter 6, Problem 6.5.12P

A C 200 x 17.1 channel section has an angle with equal legs attached as shown; the angle serves as a lintel beam. The combined steel section is subjected to a bending moment M having its vector directed along the z axis, as shown in the figure. The cent roi d C of the combined section is located at distances x_tand y_cfrom the centroid (C₁) of the channel alone. Principal axes y_l and y_vare also shown in the figure and properties I_x₁,I_y₁and 0_pare given.

Find the orientation of the neutral axis and calculate the maximum tensile stress e_xand maximum compressive stress if the angle is an L 76 x 76 x 6.4 section and M = 3.5 kN - m. Use the following properties for principal axes for the combined section:/^, = 18.49 X 10⁶ nrai⁴,/_;| = 1.602 X 10⁶ mm⁴, e_p= 7.448*(CW),_r_£ = 10.70 mm,andv_f= 24.07 mm.

Q3: An engine produce 750 kW power and uses gaseous C12H26 as a fuel at 25 C; 200% theoretical air is used and air enters at 500 K. The products of combustion leave at 800 K. The heat loss from the engine is 175 kW. Determine the fuel consumption for complete combustion.

Qu 5 Determine the carburizing time necessary to achieve a carbon concentration of 0.30 wt% at a position 4 mm into an iron carbon alloy that initially contains 0.10 wt% C. The surface concentration is to be maintained at 0.90 wt% C, and the treatment is to be conducted at 1100°C. Use the data for the diffusion of carbon into y-iron: Do = 2.3 x10-5 m2/s and Qd = 148,000 J/mol. Express your answer in hours to three significant figures. show all work step by step problems formula material science
