The moment acting on the cross section of the beam is M = 3 kip-ft. (Figure 1) Determine the resultant force the bending stress produces on the top board A of the beam. Express your answer in kilopounds to three significant figures.

Calculate the magnitude of the maximum bending stress in the beam. Enter your answer in MPa to two decimal places

For the beam I-section below, calculate the second moment of area about its centroidal x-axis (Ixxcentroid), where b1 = 10.50 mm, b2= 2.50 mm, b3 = 38.50 mm, d1 = 1.50 mm, d2 = 36.50 mm and d3 = 12.50 mm. %3D Give your answer in mm4 to two decimal places. b1 di dz + b2 b3 Answer:
