PROBLEM 5: Three equal channels are welded as shown. Given the property of one channel: Area, A = 9480 mm² Depth, d = 381 mm Flange width, bf = 94.5 mm Web thickness, tw = 18.2 mm Flange thickness, t₁ = 16.5 mm Location of centroid from web outer edge, x = 20.3 mm Centroidal Inertias: 1x = 106 × 106 mm² = Ly 4.58 × 106 mm² d Calculate the centroidal moment of inertia about x-axis (I) Calculate the centroidal moment of inertia about y-axis (I) ^ bf

Solve the problem 6

find the longitudinal strtain experienced by the strut it width is 8mm and height is 20mm

Problem: The steel pipe has an inner diameter of 2.75 in and an outer diameter of 3 in. The pipe is fixed to the ground at C, and a wrench is attached to the opposite end. The wrench is subjected to a horizontal force of 20 lb that acts in -z direction. Points A and B are located on the surface of the pipe at the same cross section. Note that A lies directly above the -y axis, and B lies directly above the +z axis. 20 lb 10 in. A B y 12 in. (a) Find the normal and shear stresses at points A and B. (b) Find the principal stresses at points A and B. (c) Show all stresses from parts (a) and (b) on properly oriented elements, relative to the given coordinate system.

QUESTION 4 There are 47 dowels - 10M, each measuring 910 mm, in a continuous concrete footing. What is the total rebar weight (kg)? (The mass of 1OM is 0.785 kg/m): QUESTION 5 The total length of a concrete beam (400mm X 600mm) is 10,427 mm. there are stirrups 10M@200mm on centre in this beam and the concrete cover is 25mm. How many stirrups does this concrete beam have?

W=50 kN/m P= 15 kN M= 135 kN*ft

Please answer by moment area method

Figure 3 below shows a cross-section of a beam consisting of rectangular sections welded together and triangular gussets for added strength. Calculate the position of the centroid C from the top for the built up section.
